A wad of curly hair found in the bathtub. If left unattended, tub tribbles will multiply asexually. In a very quiet bathroom, you can often hear them make soft cooing sounds. They will frequently grab and cling when handled, but usually they do not bite.
Wow, man. You got a serious tub tribble infestation in that bathroom.
