I'd probably be a slakoth because I don't like to move unless I have to (although I'm somehow not fat like slaking) and I'm more relaxed in most situations than I probably should be.
I was laughing for a whole minute when I read this.
I would have to choose Snorlax, I SLEEP A LOT, I EAT A LOT... but I'm skinny.. so that's one difference between snorlax and I. Also, well, snorlax is a pokemon hahaha.
