Grumble

Grumble is a mixer of a troll and a goblin and is the wife of MOUTH.

Description
Grumble has grey hair with pony tail on the side of her head, a squidward like nose, big lips, crooked eye brows, and a big mustache.

Personality
Despite being a troll and goblin who was born under a bridge is a brainiac which makes not much sense but every mii is weird so it might make more sense for her to be a brainiac.
