Don’t worry, it’s NOT canon in this verse

Ok

fireball

Yeah I'm going to make that canon to my universe now.

Also what about weenie burger?

Shadowsmellow.

Weenie Burger.

While going to panty raid a house, some demons appeared and attacked him to a painful death and sent him to hell.

Good Riddance.

Well I might have some bad news, These stories are not canon.

I know.

But I have mixed feelings for P**is Burger.

I like him because he looks cute but I don’t like him because of his personality.

Squarey

While Shadowsmellow was fighting Mixmellow, one of his shadow beings tried to kill Blocky, so squarey stepped in and sacrificed himself to save his little bro. Now he’s a soul. (Thank god it’s just a non canon thing)
