While Finn and Jake do a little dance Jake downloaded from the internet, Princess Bubblegum's Rainicorn (a unicorn/rainbow hybrid) flies by in tears. They discover that the Rainicorn is so sad because the princess is being imprisoned by the Ice King. Using snowballs, they battle their way past the Iceclops, Snow Golem, and other monsters that inhabit the Ice Kingdom to rescue her.
