Times when certain characters appeared to be a considerably different size for a certain scene, but the size change is never explained and/or acknowledged. This does generally not include rebuilt versions of puppets that might be slightly bigger or smaller than previous versions of said puppet.
- Codzilla — appears as a large monster in The Jim Henson Hour episode "Outer Space," due to being matted, and is the average size of a Muppet in "Power")
- Robin the Frog — was shrunk to literally "Tiny Tim"-size for his promotional poster appearance for The Muppet Christmas Carol, while he was still in regular scale to the other Muppets appearing on the image during one of the poster's earlier stages
- Thomas and Tessie Twiddlebug — normally scaled as considerably smaller than most Muppets, but seen in The Muppet Movie finale at their full-size
- Wander McMooch — though the same puppet is used on both occasions, he is in scale with the Gorgs and the miniature Fraggles in the Fraggle Rock episode "Junior Sells the Farm," but in scale with the full-sized Fraggles in "Home Is Where the Trash Is"
- Zoe — a smaller puppet, based on the one created specifically for her role as Mousey the Hatter Helper in Abby in Wonderland, was built for and used only during Season 40
- Grover — nose shrinks and grows out of proportions when he imagines what it would be like if it was very small, so large that the weight of it knocked him over, or the trunk of an elephant
