WoW:MoP Pet Battles
Pet Battles are a new diversion, added in World of Warcraft with its newest expansion: Mists of Pandaria. It essentially is the capturing of wild critters in the world, to train and use against other players, much like the popular game Pokémon, leading to several puns and jokes comparing them.
During his brief period in Mists, Jesse seemed to enjoy this new feature, and set about assembling an all-elemental team, to go with the theme of shamanism (his character is a troll shaman).
During the beta, Crendor introduced Jesse to this activity, and they faced each other a couple times, with varied results.
