Hicks Underground Library is a place at Purdue University. From the outside it looks small but is actually quite large inside, much like the TARDIS from the show Doctor Who. Its is a popular place for students to go and study with friends.

A Club Penguin army community full of absolute wetwipes. Typically they go on Club Penguin Rewritten and try to annoy innocent players going about their day. The HCOM is clueless as well.
Did you hear about the Underground Mafias Army again? They're a bunch of nimrods.
