Koalas are disgusting as shit. The eucalyptus leaves they eat are poisonous enough to leave them stoned 24/7, which explains why they sleep so much. They're too lazy to practice proper hygiene so they piss on themselves and notably stink of urine. They're grumpy and unsociable, and their numbers have dropped because so many of them have caught chlamydia that it's rendered a sizable portion of the population sterile.
When a Koala Pokemon inevitably gets made you fuckers can keep your stoned, STD-positive piss-soaked marsupial. Fuck.
A wombat or a part-poison type platypus would make a way better Pokemon anyway.
