They're fearless! They're adventurous! They wear underwear on the outside of their costumes! They're...Fanboy & Chum Chum! Fanboy and his wide-eyed sidekick Chum Chum are endlessly energetic "super fans" of all-things sci-fi and fantasy. These truly original kids have super imaginations and super hero costumes the likes you've never seen before. Their world is full of comic adventure (and misadventures) from an accidental case of Fanboy's teacher turning into a zombie to an ice monster running the Frosty Freezy Freeze machine. So squeeze into your tights-and your tighty whiteys-and get ready for brain freezes and FANBOY & CHUM CHUM!
