Parasite Cage

The Parasite Cage is a type of Emblem Heartless that appears in Kingdom Hearts. Appearing as the boss of Monstro, it is fought within the colossal whale's stomach.

Background
During the events of Kingdom Hearts, Maleficent sent Riku into Monstro's innards to capture the heart of Pinocchio. When Pinocchio ran away from Riku, he was captured by the Parasite Cage that rested within Monstro's bowels. Sora, Donald and Goofy fought the monster, but it escaped with Pinocchio's heart.

Sora pursued Riku into Monstro's stomach where he encountered the Parasite Cage again, only this time the creature had grown in size. The Parasite Cage used Monstro's own stomach acids to defend itself from Sora, but was eventually destroyed and Pinocchio was released.
