Parasite Cage

The Parasite Cage is a boss from Kingdom Hearts and Kingdom Hearts: Chain of Memories.

The Parasite Cage was a Heartless sent into Monstro to find and capture the heart of Pinocchio (and possibly locate Monstro's). It captured the puppet when he ran away from Riku. However, before it could succeed in escaping, Riku, Sora, Donald, and Goofy battled it in Monstro's Bowels. Eventually the Parasite Cage spit out Pinocchio and climbed away into Monstro's depths. Despite being defeated, the Parasite Cage retained Pinocchio's heart.

Sora chased Riku into the Stomach, only to discover that the Parasite Cage had lodged itself there. With Pinocchio's heart, the Parasite Cage had increased inside, and had become much more powerful. Sora battled it one last time before it was finally destroyed.

Goofy learns Cheer after the first battle. The Parasite Cage is the boss within Monstro.

Kingdom Hearts

''The Parasite Cage is quite the gourmand and eats anything in its path. Pinocchio figured out how to escape Monstro after getting gobbled up by it.''

Trivia

 * This is the only boss battle in Kingdom Hearts where Sora receives help from an ally not in the party. This trend would be used more commonly in Kingdom Hearts 2. This is also the only battle Sora and Riku would team up in until the battle against Xemnas in the end of Kingdom Hearts 2.


 * Interestingly enough, you can beat the game without sealing this world, and once you enter this battle afterwards, Riku will still fight alongside you. This makes a plot hole, since Riku is supposed to be trapped behind Kingdom Hearts.
