Gainax Ending: Finn's sickness and the nanobots merge and form a humanoid figure that proclaims that they watch you while you go number one. Then it stomps off while repeatedly shouting "Beware!". Then the short ends.
Gone Horribly Right: Using nanobots to make muffins works a little too well when they start turning everything they touch into muffins.
Good Thing You Can Heal: Princess Bubblegum gets her arm turned into muffins, but since she's made of gum, she simply molds her stump into a new arm.
Grey Goo: Princess Bubblegum even refers to the scenario by name when her nanobots start turning everything into muffins.
Mundane Utility: Instead of making muffins the old fashioned way, Princess Bubblegum tries using nanobots to make some. Lampshaded when she says, "I hope muffins aren't easy to make or I'm being an idiot."
Sequel Episode: To "All's Well That Rats Well". Finn is still sick and his sickness is what defeats the nanobots.
Working Through the Cold: Despite being so sick he can barely move or speak, Finn accepts the mission. Ironically, his sickness is what ends up saving the day.
