Super Villain Island

Super Villain Island is the 30th Island on Poptropica. It features Dr. Hare, the Black Widow, Captain Crawfish, and the Binary Bard.

Description
Deep inside a top-secret prison, four of Poptropica's most infamous villains float in suspended animation. Your mission: to infiltrate their minds and extract the sources of their evil. Can you withstand a journey to the heart of darkness, or will their twisted dreams trap you forever?

Poster Mystery
I just figured something out. If you put the Dr. Hare poster, the Black Widow poster, the Captain Crawfish poster, and the Binary Bard poster together, they'll fit together perfectly, like they're part of a big poster. Although, if you look to the very right of the Binary Bard's poster and the very left of Dr. Hare's poster, you'll see what seems to be a black area which looks like space, which seems to hint the ends of the poster.
