Tweek had stumbled upon a potion that could turn a human into a red panda. He accidentally drank a bit assuming it was coffee turning him into a weird red panda hybrid, his fur was golden the ears would stick out through his messy hair and the tail would poke out of his behind. Tweek accidentally dumped this potion into the South Park water supply turning everyone including his BF into red pandas. You were lucky enough to drink bottled water. You walked up to Tweek’s house and looked around.
