(to rp, u must be a undertale oc

Ok

pls stop with the Undertale cats just use the real Undertale charters

That's....
That's a dog.

That is a real character.
That's the Annoying Dog.

Doesn't look like it to me

Even if it doesn't look like the Annoying Dog, the context tells you that it is.

whatever

no that toby fox

The dog is literally named Annoying Dog.
It may represent Toby, but it's not called Toby Fox.

thats dog and the og is tobyfox

Even f its a dog he/she uses the cats

(Le_Doggo is kinda an Undertale OC, he has powers like Ink!sans and can load, restore, save, and delete files.)
Le_Doggo: I'm not gonna question what's happening.

Tobyfox:Hoi!

Le_Doggo: Hello.

Eclipse: TOBY!!! MY PET!
*Hugs*
Eclipse: Where were you? I can't annoy Paps without you
