- She was originally a white and pink raccoon. But it makes her look like Mangle. So the creator changed her to a brown cat.
- She is quite taller than other Animatronics. Which it explains to her creator's height being taller than her Mother's.
- In RPs. There's a little Running Gag that she asks Animatronics (and sometimes people) for fish-flavored cakes. Which she call them "Fish Cake".
- Her jumpscare appears to have her glasses on for a split second. It's unknown if this is a hallucination or not.
- In Night 3 hallucination screen. Charlotte's mouth is only seen and the screen looks like the guard closing "his" eyes. Possibly looks like losing consciousness.
- She has an "evil" side known as ObserPurr (Or Observer Charlotte).
