With so many banners and units that can be grinded in levels and challenges or bought from the shop, you need to know which ones are worth it. SpongeBob TD has some trap units that need to be avoided and some really powerful must-have ones. Here’s my best SpongeBob Tower Defense unit tier list.

Best SpongeBob Tower Defense Unit Tier List

Best SpongeBob Tower Defense Unit Tier List

I’ll rate SpongeBob Tower Defense units from S-Tier to F-Tier. The S-Tier and A-Tier are usually Secrets, Mythics and Legendaries that you want to roll for in Banners. B and C-Tier are units that are outclassed in power but still strong as secondary carries or starters. Lastly, D and F-Tier are units that are underpowered or should usually be replaced when you get better ones.

S-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
Mega Kraken Karen	Exotic	This is a power creep unit that outclasses most of the secrets with massive AOE damage and a bonus charge ability. A money grab unit in my opinion since the Kraken Crates are so expensive in the Shop and rare to get in Prizes. I’d recommend getting Kraken through trading since the trade value is dropping with each day.
Olympian Spongebob	Limited	This is one of the best units in the game if we’re going by pure stats, it’s so powerful and can compete with a lot of Mythics and Secrets if not all of them.
Dennis	Secret	Dennis is a powerhouse of DPS and the majority of it comes from the Burn effect. Secrets have been slacking lately but with the Sea Bear buffs and Dennis’s excellent DPS, they’re carrying hard,
Cyborg Plankton	Secret	With the recent buff, this is the best tower in the game stat-wise if you get lucky with a drop.
Smitty Werbenjagermanjensen	Mythic	Some of the best splash damage you can get among Mythics.
Sea Bear	Secret	Sea Bear’s got amazing stats and deals incredible damage up there in the ranks with Cyber Plankton.
Bubbles the Dolphin	Mythic	One of the best Mythics in the game right now if you can get it via the Pass. It’ll carry you through any level.
Jojo	Legendary	Like Handsome Squidward, Jojo competes incredibly well with Mythics and is in S-Tier due to amazing single-target DPS. It’s one of the best Legendaries and even though it has low range it deals amazing damage.
Alaskan Bull Worm	Secret	This is a powerhouse of damage and AOE. While not the best unit in the game, Bull Worm has amazing Pierce for multiple enemies in its path and applies Frostbite which slows like Handsome Squidward and deals damage-over-time.
Hash Slinger Slasher	Secret	One of the highest DPS units among Mythics and Secrets.
Richard	Mythic	Unlike many of the previous updates, Update 10 brought some of the most powerful Mythics in the game and Richard is one of them.
Captain Magma	Mythic	While I wouldn’t go as far as to dive into the hype and say Captain Magma is the best Mythic, he’s still quite strong. Some of the best focused AOE damage in the game. Grab him in Raids ASAP.
Realistic Fish Head	Mythic	An excellent AOE tower that I would build around for late-game comps.
Sea Rhino	Mythic	While it’s got a really low trade value, the Sea Rhino is incredible stat-wise. It’s weaker than its counter-part Sea Bear but it’s still an excellent carry unit.
Barg’N-Mart	Epic	Another must-have farm unit for economy in addition to Krusty Krab. Bring this or Krusty Krab always.
Lord Poltergeist	Mythic	Lord Poltergeist is the upper end of Mythics and one of the best Mythics to come out in the recent updates with incredible DPS for Mythic standards.
Krusty Krab	Rare	One of the two farm units in the game. It’s incredibly useful on any game mode to build up your economy. Bonus points if you can get a Shiny Wumbo version.
Sponge Henge	Secret	The Sponge Henge had a lot of problems and was weak but now it’s finally been fixed to do insane damage. Hype!
Dream Gary	Secret	This is the META unit with incredible carry potential because he stuns on every hit and stacks with Handsome Squidward’s slow.
Bert	Mythic	Not only does Bert apply slowing like Handsome Squidward but it has an addition damage boost due to Poison as well. It’s not the best Poison DPS but combined with slowing it’s pretty competitive.
Squidward (Handsome)	Legendary	The best Legendary in the game and while Mythics outdamage it, you want it for the slow to support other Mythics. So it’s S Tier in terms of support, not damage.
Dungeon Master	Secret	While not the best Secret, Dungeon Master does great damage and can carry you through grinds with his Pierce. Overall the best medieval set unit.
Robot Mantis	Secret	Just an overall strong unit and one of the better Secret units with great damage. It’s even better considering you can get it for free by just AFK-ing for 1000+ hours and getting all Lazy Lagoon achievements.

A-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
Madam Hagfish	Mythic	Probably the strongest A-Tier unit with Pierce with a decent attack speed and amazing range. She’s not Sea Rhino DPS level so I decided to go with A-Tier but she’s a strong contender for S-Tier.
Lion Fish	Limited	Essentially Lion Fish fights like the Sea Bear but with overall lower DPS. Still great though, just lower A-Tier.
King Jellyfish	Secret	You get this one just by playing the game through Prizes and perhaps this is why it’s kind of the weakest Secret in the game for me. It’s not OP like most of the Secrets even though it’s fun to play. It just doesn’t deal as much damage as you’d expect from a Secret but I’m hesitant to put it in B-Tier so far so A for now.
GG Rock SpongeBob	Mythic	The GG Rock is the best A-Tier unit and can sometimes even be lower S-Tier.
Sir Spongebob	Mythic	The second-best medieval set unit with great damage that can carry you if you don’t have Secret units.
Secret Agent Star	Limited	Not the strongest limited unit but not the weakest either so it’s mid when it comes to Secret-Mythic-Limited standards. Definitely a good one to get for Trade Value though.
Granny Tentacles	Epic	One of the best if not the best starters in the entire game. This Epic will carry your early game in any game mode.
Dream Patrick	Legendary	One of the strongest legendaries to come out recently and one of the best Legendary DPS units overall.
Hibernation Sandy	Mythic	Massive range from the start and excellent DPS once you upgrade it that you can’t go wrong with.
The Quickster	Mythic	Many in the community feel like The Quickster isn’t the best because of his low flat damage but many also fail to notice his overall excellent AOE DPS. His attack speed is through the roof and if we’re talking raw DPS when you place him in the middle of a group for AOE, he can duke it out with the best of them.
Easter Bunny SpongeBob	Limited	Unironically, Easter Bunny SpongeBob is a decent unit with pretty great stats and good Splash. So besides the trade value it’s a great unit to keep for runs.
Spot	Legendary	Spot is in the upper end of Legendaries with great damage and attack speed.
Band Geek Mrs. Puff	Mythic	The only Pierce unit from the Band Geeks and an overall decent Mythic to roll for. I prefer Band Geek SpongeBob due to Line AOE but this is an excellent alternative.
Dirty Dan	Mythic	Dirty Dan is actually a pretty decent summon Mythic with great attack speed and decent damage dealing out above average DPS for Mythic standards. Excellent if you’re a beginner as a Summon Mythic.
Mermaid Man	Mythic	While it’s good raw damage, it’s a single-target attack tower with no utility so it’s not as good as other S-Tier Mythics.
King Neptune	Mythic	In terms of Mythic power levels, Neptune falls behind some of the Mythics slightly but he’s still a powerful unit. Just not S-Tier powerful.
Man Ray	Mythic	Outclassed by other Mythics due to its low attack speed. I wouldn’t roll for it in a banner but it’s still better than most Legendaries.
Band Geek Mr. Krabs	Mythic	A decent Splash damage Mythic that’s on the lower end of Mythics but still excellent compared to Legendaries.
Handsome Plankton	Mythic	Not the worst and not the best Mythic but overall Handsome Plankton is great to keep for off DPS. He’s not even close to being as useful as Handsome Squidward though who brings that slow utility.
Band Geek Squidward	Rare	The best Band Geek starter unit and one of the best starter units in the entire game with decent Full DPS.
Band Geek SpongeBob	Legendary	One of the better Band Geek DPS units reaching up to 12,5k damage with Line AOE.
Flying Dutchman	Legendary	Just a generally useful A-Tier unit to carry you as a beginner but not as powerful as Mythics.
Perch Perkins	Legendary	Perch Perkins can’t compete with the Mythics and most of the Legendaries due to mid Leggy-standard DPS and awkward attack patterns that sometimes miss if place incorrectly. Still a good unit due to Leggy stats but not the best Legendary in the game by far.
Pinhead Larry	Mythic	It’s an alright new Mythic compared to Legendaries but it’s not even close to being a good Mythic due to underpowered stats.
DoodleBob	Legendary	An excellent Legendary because it has good damage, speed, and range.

B-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
King Krabs	Mythic	A disappointing Mythic but competes with Legendaries in B-Tier and lower-end A-Tiers, overall the worst medieval set Mythic.
Gladiator Patrick	Mythic	Decent in boss fights but for overall tower defense grind it’s not the best Mythic you can get so I would skip it unless you’re collecting all units.
Glove World Spongebob	Legendary	This is a decent Splash AOE Legendary that’s in the middle in terms of power between Mythics and Legendaries. There are better ones, but this one does a fine job for story and quests.
Sand Creature	Epic	This is one of the best if not the best Epic unit in SBTD due to excellent Full AOE and great range. It can’t compete with prime Legendaries and Mythics but it’s close.
Tattletale Strangler	Mythic	Good AOE and great for beginners but the low range and and mid damage puts it in B-Tier.
Dark Knight	Legendary	Dark Knight is nothing special in terms of DPS nor extra effects so it’s a pretty mid medieval set unit.
Plankton	Legendary	Decent stats and no weaknesses but is outclassed by Mythics and most Legendaries in terms of upgrades.
Tiff	Mythic	Honestly Tiff is a huge disapointment since it has the worst stats out of any Mythic unit both between the new and the old ones. It’s still better stats than some Legendaries and below so it’s B Tier but it doesn’t fit the standards of Mythic unit.
Dirty Bubble	Epic	The best Epic tower in terms of DPS.
Sir Patrick	Legendary	About the same power level as Dark Knight and both of them are mid-tier medieval set units.
Mr. Krabs	Legendary	That slow attack speed is rough, I wouldn’t go with Mr.Krabs in any comp but if you get him, his damage does ramp up quickly.
Miss Appear	Legendary	Her line attacks are pretty decent but she’s not the best overall Legendary. She’s great in specific situations when you can place her so she hits in a line.
Band Geek Sandy	Rare	The second best Band Geek starter unit and the top 5 best starter unit in the game with decent Line AOE damage.
Mermaid Man Spongebob	Epic	While not a carry for the later waves, Mermaid Man Spongebob is an upper tier Epic unit that’s great for farming and starting out with.
Band Geek Pearl	Legendary	A Full AOE damage unit with good stats that is ruined by her animation. It’s so clunky it makes her worse. Once they fix it it’s A-Tier.
The Elastic Waistband	Rare	One of the best Rares due to excellent AOE damage for its rarity.
Slappy Laszlo	Rare	The best Rare for its utility because it can slow down units and support your other towers.
Atomic Flounder	Epic	Decent attack speed that sets it apart from other Epics but the overall DPS isn’t worth A-Tier.
Snow Mollusk	Legendary	I wouldn’t grind Challenges for this unit as it’s not the best when compared to other Legendaries. Only grind for it if you’re a completionist and want to collect all units. It still has better stats than most Epics and below, but it’s not worth the grind.
Pearl	Rare	An excellent starter that can compete in the B-Tier.
Soaring Starfish	Limited	The Soaring Starfish is the opposite of Sea Rhino. It’s got an amazing trade value but really bad stats despite Splash compared to Legendaries and Mythics. It’s a collector’s item that is mechanically weak.

C-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
Larry The Lobster	Epic	The best C-Tier unit. Larry is similar to Plankton in that he’s overall a great unit that gets outclassed with upgrades by others. Still a pretty decent tower for beginners.
Band Geek Plankton	Epic	A decent Splash damage unit for beginners.
Band Geek Patrick	Epic	A decent Line damage unit for beginners.
Planktonamor	Epic	The second weakest unit in the medieval set and overall a mid starter, nothing special here, just your regular beginner friendly Epic unit.
Karen	Epic	Tango Karen might be higher than regular Karen but I’m putting Karen above just because I really don’t like the Tango version.
Grandma Square Pants	Rare	The best single-target damage Rare in the game and an excellent starter.
Tango Karen	Legendary	One of the worst Legendaries in the game, and it’s no surprise because you get it for free in the Chumb Bucket map. I wouldn’t use it.
Princess Mindy	Epic	Just a mid-tier unit with nothing special to say about it.
Texas Sandy	Epic	Great for trading but otherwise a mid-tier Epic.
Patty Obsessed Squidward	Epic	While popular for trading, POS is one of the weakest Epics in the game.
Squilliam Fancyson	Rare	A pretty good starter due to its good opening AOE damage.
Old Man Jenkins	Rare	A decent rare tower as a starter until you get better ones.
Barnacle Boy Patrick	Uncommon	Easily one of the best Uncommons due to its raw damage and an excellent beginner unit for grinding Hard mode early.

D-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
Bubble Buddy	Rare	An okay starter with decent damage that you’ll replace once you get better units.
Squidly Tentacles	Rare	The worst unit in the medieval set and generally not the best starter either so you can skip this one.
Mrs. Puff	Rare	Nothing special to say here, just replace it once you have better ones.
Lord Royal Highness	Rare	Another tower to replace once you have better ones.
Karate Sandy	Rare	A decent starter but there are better starters in the upper tiers. Good for trading.
Kevin C. Cucumber	Rare	Worse than other Rares in terms of stats.
Karate Spongebob	Uncommon	An okay starter but people are trading him a lot.
Jim	Uncommon	Better than most Uncommons so it’s slightly higher in D-Tier.
Goofy Goober Waiter	Uncommon	Stands out from Uncommons with slightly better stats.

F-Tier SpongeBob TD Units

Name	Rarity	Ranking Explanation
Baby Prunes	Epic	You can get Baby Prunes from the Shop but I wouldn’t recommend it since it’s not the best unit both in terms of stats and utility.
Barnacle Boy	Uncommon	Just a replaceable subpar tower in terms of stats.
Gene Scallop	Uncommon	/
Bubble Bass	Uncommon	/
SpongeBob	Common	There are no sleeper OP commons in this game as they’re all pretty weak so they’re all in F-Tier.
Squidward	Common	/
Sandy	Common	/
