Making the scary monsters scarier?

[Ssschah]

Is it possible to edit what the monsters look like? IF you could with an editing program or whatever, that would be awesome, because you could make it scarier, or in my case funnier. I would make its mouth touch the ground and hang. That would make me scream my head off

Ofcause its possible if you have the tools(programs) and the skills to do such a thing
