Monstro

Monstro is a huge whale from Winnie the Pooh meets Pinocchio who swallowed up our heroes when they were looking for Geppetto. Pooh and his friends ended up confronting Riku inside Monstro, who had been corrupted to the Dark Side by the Villain League. Monstro eventually sneezed out Pinocchio, Geppetto, and our heroes, and was killed by crashing into a large sea cliff.
