A spoof poster of Ice Age: The Meltdown as seen in the background.
Cold Age: The Smackdown is an advert parody of Ice Age: The Meltdown seen in the South Park episode Cartoon Wars Part II. It is seen in the part when Kyle fights Cartman to stop him from canceling Family Guy. The billboard shows a creature that looks remarkably like Scrat. This is among many Fox references along with The Simpsons and King of the Hill. Also at the time of airing, Ice Age: The Meltdown was number-one at the US box office.
