- In Hamuchanzu de Gozaimachu! Vol.2, Cook Ham is referred to as Sushi Ham (すしハムくん). His name was changed to Cook Ham in the first movie, presumably due to his assistants going by the "Sushi Ham" name instead.
- There are two distinct designs of Cook Ham; the "movie version", with a beard and tan fur, and the "manga version", with no beard and white fur. The headband and outfit are the same between both designs.
