Dream Land asked Kabu for help. The first time the people of Cappy Town saw it was when it ate sheep and flew in Castle Dedede. King Dedede and Escargoon had no idea of its capabilities until they were attacked by it. Kirby used Fire and help from Meta Knight and the Warp Star to defeat it. This is how Kirby proved that he was a hero.
Name Origin Edit
Oct means "eight", which is how many arms an octopus has. Con means "bad", which is the nature of this monster.
