Grillby is the protector of all flames in the Underground.[1]



Grillby is a monster who's made of fire. He wears hypno glasses, a blue suit, a yellow shirt with a pink tie bow, blue pants and yellow pointed shoes. He carries a green jug.[3]


Grillby is wacky and demanding.[1]

Main Story

Grillby wants Chara to buy his food, so he can buy the flames in the Ruins a heated limo, in which they can escape through Snowdin without getting hurt.[2]

He has two fire backsales, with the second one being very overpriced.[4]


  • Grillby might charge his friend Heats Flamesman after Chara as one of his attacs during his fight.[5]
