- Edited for Syndication: The last scene of "Sno' Fun", of Powerful Pierre using his sledgehammer to crack rocks over his head, was cut out. A theatrical print of the cartoon with this ending intact is up on YouTube.
- Keep Circulating the Tapes: None of their cartoons have seen an official DVD release, and the only short that's easy to acquire is their debut "The Talking Magpies", by virtue of it being in the public domain.
- What Could Have Been: "Mechanical Trouble" was intended to be a 1964 cartoon. It was storyboarded but it never went beyond that.
