Guara Game Character

This is the main character of a pretty simple children's game my team is developing.
He's known as Umum, Guarumum, or Guaramon as I call him (Like a Digimon. No reason, pretty random.) Actually, the ugly nicknames were made to annoy me, since I'm his mother, but I got over that now.
He's obviously(?) a Guará wolf, found only in Atlantic Forest.
THAT'S RIGHT, NOT A FOX!
