Rachel's got some pretty strange stuff happening. She can't control her morphing. One minute, she's doing homework. The next, she's morphing a full-grown crocodile and without returning to human form, she becomes an elephant. That's when the floor gives way and Rachel finds herself looking up at what used to be the kitten ceiling. What's going on? No one's sure but Rachel and the other Animorphs have to figure out, quickly. Because if someone sees Rachel's out-of-control morphing, the other Animorphs and Ax are in some serious trouble.
