Adventure Time's favorite gender-flipped duo is back with an all new caper! Cake is a Card Wars champ who can't be beat, and Fionna...is really tired of getting beaten! They set off in search of a challenger who can really test Cake's mettle. When they stumble across some gamer slugs, they think they've hit the jackpot, but these guys have never heard of Cake and refuse to even play with her!
