What three animals make up the Chimara Percy Jackson lighting thief?

In "The Lightning Thief" by Rick Riordan, the Chimera is a monstrous creature composed of three animals: a lion, a goat, and a snake. The lion represents the body, the goat emerges from its back, and the snake forms the tail. This fearsome combination makes the Chimera a formidable adversary for the protagonist, Percy Jackson.
