Beck is not seen in the first half of the episode but is shown on the wheel app Robbie spins and helps build the cupcake float
The episode's title is a reference to the film "Nightmare on Elm Street".
Sikowitz breaks the fourth wall, saying how none of the other students in his class really speak or do anything, only sitting there and reacting to a situation.
Beck was absent for the first couple scenes of the episode, and doesn't show up until they are in the cupcake. This is interesting because Beck should've been in Sikowitz's class, although he might've been sick that day or had other plans.
Sesame Street is mentioned in this episode Cat briefly sings the theme song before Jade interrupts her.
