I'm surprised no one said mew! (or did they??) You could fly, transform, and learn any TM move so do virtually anything. You could stay and play under water and at high altitudes for long periods of time, and at night enojoy stargazing above the clouds *_*
You could teleport and create neat big pink bubbles to bounce on, too! ^_^
Yeah, I'd want to be a mew. No work, all play XD AND you could be cute! :P
I'm a loner, but I'm alo very hyper and playful so I think mew would fit me perfectly X3
