The Abominable Snowman' is a villain from the comic book "Snow Day".
The Powerpuff Girls were sent on a wild goose chase around Townsville, having to stop a bunch of crimes and save a bunch of lives, on the snow day, they were supposed to have off from school. Buttercup was so mad about having to do so much work on their day off, that she kicked a tree in rage, which caused an avalanche on a nearby mountain, inadvertently awakening the Abominable Snowman, who was sleeping in an ice cave. Infuriated with being woken up from his slumber, The Abominable Snowman started destroying The City of Townsville.
Meanwhile, The Powerpuff Girls were staying at home and they decided to swear off doing anything else heroic for the rest of the day. The Mayor sent them a distress call about the Abominable Snowman and begged them to save the day. The Powerpuff Girls sadly went along with this and went to stop him.
Buttercup was especially very mad about having to ruin her day off because of the Abominable Snowman and was ready to let him have it. Blossom and Bubbles punched him across the face left and right and even took some pounding to his belly, while Buttercup cracked him on the head with an uprooted tree and also smacked him into a nearby building made of concrete, knocking him out cold. Buttercup was ready to continue attacking him but Blossom and Bubbles had to hold her back, once they realized the Abominable Snowman was defeated and had finally had enough.
