Hey, there's ALOT of Poke'mon, they all level up at different levels, some neeed special stones, and others don't evolve.....
Wait, level up? Go around and battle to get experience points, check how much experience points they need to level up, and heal them occasionally
Tip; Put your weakest pokemon in front, then when you're in battle switch it straight away with a stronger one, and both end up with experience points.

pika freak holy shit that must of took a long time
