Pumpkaboo
Here is a Pumpkaboo I made 3d printable take the obj. I found online. It might be better off if you attach a base to it so it can stand since its chubby legs cant hold it up. Its the pokemon used by Team Rocket. I did a lot of sculpting on it to smoothen it out and get it looking good.
Update:
Added a version with base for easier printing and displaying.
