The Fire Rat is one of the many characters assimilated with the Fire-Element. They tell Jalapeño Pepper that his cooking stinks after he tried to smash them. They were on Jalapeño's head when they said this, so after they said it, they jumped off, and Jalapeño smacked himself with his own mallet.
They appear to be a rat with features similar to all of the other Fire-Element assimilated characters. They have blue cracks all over their body and a blue flame over their head.
Like all of the characters that were assimilated with the Fire-Element, he seems to crave battle and only care about themself.
- This is the only rat that we see in the series actually talk.
