The Flea forgets to wash his hands before making donuts and (by forgetting it) he makes a donut that comes alive, so he calls him "Sprinkles." One day, he tries to eat Sprinkles, so Sprinkles tries to escape and revive all the donuts. Rikochet and Buena Girl were tied in donuts and The Flea frees them. Finally, Flea tells Sprinkles that he is sorry, it seems that The Flea eats Sprinkles completely at the end.
