This is another Pokemon by PMF.
This is Rattata, first seen on the first episode of the anime trying to steal food from Ash's bag.
The trickiest part to this craft is the mouth. It's hard getting back behind those huge teeth to form the bend in the mouth. I think if you're going to build this, it's better to build the lower portion, the cheeks and the chin and the mouth first before you add on the nose, eyes and ears. That way, you have more space to work on the mouth.
