Mister Tobysters

Mister Tobysters is an Annoying Dog recovered from a Birdtale Genocide Timeline by Kit-sune. He lives with Gane and his finicky, playful, and friendly. He likes food and always enjoys to play, however he has shown that he is not just a "dog" in all terms of the word. He has been shown to read and write, even respond to commands the first time when they are mentioned.

This is mostly because this is the Monster embodiment of the creator of Undertale, Toby Fox.

Very good doggo.
