Okay, so there is a weirdo celebration on Candy Kingdom were some tarts are eaten somewhere. So Bubblegum gives Finn & Jake the mission of bringing the tarts to the place cause Cinnamon Bun is kinda crazy and the Tart Toter has gone senile. So Finn comes up with a plan: he will give Cinnamon Bun some tainted tarts and let him go through the common path so that if someone steals them it won't be a loss while they go through the desert.
But in the desert some hobos steals some tarts and a butterfly with a lser steals others leaving only 2 that are later stolen. At the ceremony, everyone is eating Cinnamon bun's tarts and as it turns out, Cinnamon had the normal tarts while Finn & jake were carrying the other tarts (title!).
Overall: So it was a fairly average outing of Adventure Time. but the butterfly with a laser was hilarious. So 8/10.
