|Occupation||Princess Bubblegum's lab rat|

|Latest appearance||"The Suitor"|
Science is a candy corn lab rat that appeared in "From Bad to Worse." It is in a cage on Princess Bubblegum's table. It was trained to perform complex scientific related tasks. Princess Bubblegum tries to tell Finn that "Science is my rat!" but turns into a candy zombie in mid-sentence. Once he finally figures this out, Finn releases it out of the cage for it to make the zombie formula that cures all the zombies. At the end of the episode, it is awarded a medal from Princess Bubblegum for saving the Candy Kingdom.
Science looks like a piece of candy corn with ears, an orange nose, feet, and a long yellow tail.
- Science's key role in "From Bad to Worse" is appropriate because it looks like candy corn and the episode was the Halloween special.
- Although Finn nearly died by covering himself in the antidote in "From Bad to Worse," Science received the medal. This was because Science made the antidote.
- It is implied that Science is a female when Finn asks Science, "What is it, girl?"
- Science's tank has a label on the bottom left corner that reads "Ts-19 04." Ts-19 or test subject 19, may be a reference to the Walking Dead television show, in which Edwin Jenner, a scientist at the Centers for Disease Control, labels his wife TS-19 after she is infected with the zombie virus.
