Racatans are monsters that are usually peaceful. But they turn huge into a giant fire-breathing beast. When it turns huge it has gigantic narrow horns, sharp teeth, red fur, creepy angry eyes, T-Rex arms, and it also breaths fire like a dragon. Juniper Lee accidentally got one mad. She was sent to capture it, because the leprechauns released it in the woods and it caused deforestation by eating trees and making forest fires. Juniper and Ray Ray released a Genie from its' jar to defeat the Racatan. After the Genie was released, he caught a whiff of the Racatan and grabbed it,targeting only evil creatures. During the credits, the Genie and Racatan were singing on the stage of a night club full of monsters (even a leprechaun).
It is said by Monroe that the Racatan's tail has an only weakness where the Racatan can be defeated. This was the key to defeat him at the Cartoon Network game Out of Charm's Way.
These creatures are very dangerous and somewhat evil. They may look cute in their normal form, but if someone pokes it, it will get mad and turn even more dangerous. When someone asks it to leave, it will ignore them and will continue to do their own thing.
The Racatan appears in the online games Party Interrupted and Out of Charm's Way despite being a one-time antagonist. The first is a re-telling of the first episode's conflict in game format and in the other game, the Racatan is the first boss fight.
