Octacon is the first monster that King Dedede ordered from Nightmare Enterprises. He is a humongous, evil red octopus whose favorite food happens to be sheep and sardine. The fact that he ate several of the Cappies' sheep is the reason why Kirby crash-landed in Cappy Town. Before Kirby's arrival, the Cappies were suspicious of Dedede's pet octopus and went to Kabu for advice. He foretold that a pink Star Warrior named Kirby would come to the Cappies' rescue and defeat the monster, which is where Kirby's arrival came in. Dedede tried to make the Cappies think that Kirby was the monster eating up all the sheep, but the Cappies were so suspicious of his pet that they didn't believe him.
