Lol, I would probably choose Snorax. Eat and sleep as much as you want...and no one can do anything about it in fear of getting sit on.The whole world can be your bedroom and kitchen at the same time.;)
It might be a Grovyle, it looks pretty small for fighting in good spirit, but it sure does stay cool when meeting Pokémon that make him act cool that he think he could win. :D
