This episode is notably one of the only ChalkZone episodes to recieve a home media release, and the first one to do so. It was released on the 2003 VHS Nickstravaganza!, which was only sold at Walmart. The video also included episodes of SpongeBob Squarepants, Rocket Power, and The Fairly OddParents. A DVD was not released.
This episode marks the first appearance of Craniac 4.
Craniac 3 makes his final appearance in this episode.
This episode reveals that only Rudy can use the magic chalk.
This episode, along with "Snapmobile" and "Rudy's Date", which it was paired up, was supossed to air as the second episode of the series, but was aired as the fourth episode.
The background music cue that plays when Penny and Snap are locked in the kitchen of the future was also used at the beginning of the first Oh Yeah! Cartoons short for The Fairly OddParents. This would mark the third time in the series where a background music cue from The Fairly OddParents is used.
When Penny tells Craniac 3 that it takes a real human artist like Rudy to use the magic chalk, Rudy's outline gets unusually thicker.
When Rudy draws another door to the kitchen of the future to rescue Penny and Snap, he's incorrectly holding the chalk in his left hand, despite being right handed. It could be possible that he was drawing with his right hand then switched the chalk to his left hand to open the door off-screen, however.
Rudy is holding Craniac 4's arm at the end of the episode, however he did not have it when he, Penny, and Snap were leaving the Dome of the Future.
Craniac 4 is accidentally credited to Robert Cait, when he was actually played by Rob Paulsen, and the robotic chef in the kitchen of the future was accidentally credited to Rob Paulsen, when it was actually played by Robert Cait.
