Looks like most people had Panpour as their monkey pokemon. I, as well had Panpour and used it pretty much throughout the game, I just found it easier to keep it along with my team to find and train up other pokemon, it was also useful for certain HM's so that always came in handy. Believe it or not, that pokemon won me some pretty tough battles later on. Though, honestly, it's not the best Pokemon out there.
