- This episode was paired up with a rerun of "The Haunting of Star House" during the original American airing, but since it has re-airing with "I Smell a Pat."
- The poster behind Squidina during her interviews is similar to the official poster of the series.
- After Squidina drinks some coffee, she says "I'm ready!... to get this show on the road!". This is likely a reference to SpongeBob's iconic line, "I'm ready!".
- This is the fourth episode of the SpongeBob franchise where Pearl is seen without Mr. Krabs, following "Tunnel of Glove," "Patnocchio," and "Goons on the Moon" respectively.
- This episode's title is a reference to the phrase "Santa's little helper," often used to refer to Christmas elves.
