Gnome

Gnomes make their appearance in The Enchiridion, found yelling help in a pit of fire. After being rescued by Finn and Jake, instead of thanking them, they began destroying Old Women. Finn runs away since he doesn't know what to do. The Gnomes attempt to destroy Jake, but he dodges their blast attack and puts them back in the fire, where they begin to yell helplessly once again.

Appearance

In Righteous Quest
The gnomes appear as enemies in in the first stage of rigteous quest. They can shoot small blast of lightning.
