- What Could Have Been:
- Little Cheese was originally named Big Cheese, and he was actually mouse-sized with the ability to grow.
- When Roy Thomas and Scott Shaw! were creating the comic, they came up with a Zoo Crew member who they never used: Whirlibird, a female bird with Everything's Better with Spinning powers who was based on Thomas' wife Danette.
- Ruby-Spears planned an Animated Adaptation of the comic—which would have replaced Alley-Kat-Abra with Wonder Woman. A pilot script was written, but never produced.
