Banned in China: The episode was banned in some countries along with "Patty Hype" for one obvious reason: the horrifying close-ups of Wormy that pop up thrice.
Portrayed by Different Species: In the episode, we get a live-action Gross-Up Close-Up of the face of Wormy after he transforms into a butterfly (specifically a Monarch). However, the insect in the close-up shot is a horsefly, not any kind of butterfly.
