Invader Zim (Invader Zim #34)

Who's in prison? ZIM's in prison! What did he do to get there? No one knows! Not even him! But Moo-Ping 10 is the most notorious Space Prison in the whole of the Irken Empire, and ZIM better get out soon, or he could end up rotting in a space cell for the rest of the comic series, and that would be very, very bad for sales.
