- This is the fourth special to be a clip show, the first being "Patchy's Playlist," the second being "SpongeBob Appreciation Day: Patchy's Beach Bash!," and the third being "The Stars of SpongeBob Fan Favorites Special."
- Despite that this is a special that is Halloween-themed, not every Halloween episode is included. "Séance Shméance" is not included.
- In the event, a clip from "House Worming" was shown in a cropped 4:3 aspect ratio despite the episode being produced in widescreen.
- All of Potty's lines are archival recordings reused from previous episodes.
- Every time the outside of Patchy's house is shown in this special, it's a night time shot taken straight from the ending of "The Sponge Who Could Fly." The only differences being is that it's cropped to widescreen and doesn't have a SpongeBob constellation above Patchy's house.
- This special got 0.72 million viewers, making it the least viewed special thus far.
