Jenny: He's...he's everywhere! He could be in this cake, or in this punch, or this present! (screams, flies in the wrong direction, hits a wall, then flies in the other direction and destroys a door)
Tuck: Told you she'd be surprised!
At one point, the Wound the World salesman calls Killgore "Kilroy", a reference to the song "Mr. Roboto" by Styx, which is about Mr. Roboto doing menial jobs in a prison and a rock star named Kilroy overpowering it and using its hollowed out shell as a disguise to escape said prison.
This is the second episode that marks the instance of Jenny crying, the first being Raggedy Android.
Dan Castellaneta, who voices the Teacher and the Cluster Robots, also voiced Homer and various other characters from The Simpsons.
Tara Strong, who voices Killgore, has voiced numerous characters from other Nicktoons, such as The Fairly OddParents and Danny Phantom.
