Pupil Worm

Nerd Worms appeared in "The Real You". The worms are attending a class on "Theoretical Fightonomics" at a worm college, located inside of a massive rotten apple nearby Tree Trunks's house.

Finn and Jake disguise their fingers to look like worms so they can get into the class and give fake names. However, the name Finn chooses is "Wormy McSquirmy", a student who signed up, but had never attended class. The worms are angered by this and attack their disguised fingers, but Finn and Jake easily push all the worms into a wall, which hurts them. Finn and Jake escape. The worms professor shouts at them to "Stay out of academia!" then gets his head stuck in the window hole.

Appearance
They have almost exact appearance to the regular worms but they are a slightly more yellowish green color. Some are shown wearing glasses.

Trivia

 * They might be a play on the word "bookworm".
 * Professor Worm's voice is the same as Grandpa Squarepants from Spongebob. This may be a reson why Tom Kenny voices Ice King.
