As you touch the bar, a red light goes on at the tip. A tinny voice comes out of the bar.
"Log 123. December 12, 1948. Caught one of them. It looks like a blob of fake vomit. I have it caged and will proceed to experiment."
The light on the bar goes out as the voice stops talking.
"Very good," squawks the walkie talkie, "hold on to that communicator, you're going to need as many as you can get. Now, proceed into the courtyard, and watch out for any jacked-up spoonbenders."
