puke-a-chu

A person who can't hang during a night out of drinking typically evolves into this rare pokemon species. Its only skill is puking at unexplainable and unpredictable times. Despite its rarity, no Pokemon Master wants to catch it. Besides, it will probably stink up the pokeball. It's natural habitat is anywhere near vodka and whiskey--all at once.
