"IMAGINATIONLAND" TRILOGY - SYNOPSIS

The doors of a whole new dimension are thrown open and the boys of South Park walk right in. It all begins with Cartman's quest to find a leprechaun and in turn, win a bet with Kyle that would force him to suck Cartman's balls. The kids have just arrived in Imaginationland, a wondrous, magical place, when terrorists attack, unleashing all of mankind's evil imaginary forces upon the world. With imaginations running wild, the government steps in and prepares to nuke Imaginationland thus eliminating further attacks on the country's most vulnerable spot. A crisis faces the nation and Stan and Butters remain trapped in Imaginationland. Kyle pleads with the Pentagon for his friends' lives and Cartman goes all the way to the Supreme Court to get justice for his dry balls.
