The Fatheads VHS tape is orange. The Nickelodeon tapes from the 90s were all Nickelodeon orange.
Instead of using tablets to draw the storyboards for this special, it was actually storyboarded by hand, which doesn't happen very often these days.
The special was originally intended to air on Nickelodeon in 2018, the same year production was completed, but released on Netflix in summer 2019.
The picture next to the Fatheads at the beginning of the their special is actually a picture of writer, voice actor and The Fatheads creator, Mr. Lawrence, who voiced Filburt and co-wrote the script.
