Push, the trash can from "The Towering Wilter", makes a brief appearance during the big sneeze scene.
The NYRD Award subplot mysteriously vanishes after Rudy & Penny's argument.
(Skrwal and Craniac describing their plan) Skrwal and Craniac: Look, look, look, what we wrought. Our own Rudy ro-o-bot. All who see-will think that he-is young master Tabootie. Skrawl: We're going to send him strolling to Chalkzone for some magic chalk, magic chalk. Craniac: He'll be so sweet, Biclyops won't realize he's designed.... Together: To destroy the chalk mine. And we'll have-what we crave- chalkless Rudy as our slave. And we'll sit-on the throne- we'll be rulers of chalkzone!
The title for Double Trouble is not in a chalkboard like the other episodes.
Robo-Rudy losing his "skin" near the end of the episode is a reference to "Terminator".
