- "Can't hear you, Peach."
- —Other members of the Tank Gang, when Peach's voice is muffled against the glass.
Peach is usually seen attached to the side of the tank watching the dentist do his dental work. She announces what is going on to the rest of the Tank Gang, however, whenever Peach speaks, her voice is muffled against the glass (which is a running gag) and one of the other fish would say, "Can't hear you, Peach." She then unsticks herself from the glass so the gang can hear her clearly. At the end of the film, Peach can be seen moving up with the credits while clinging onto the screen. She suddenly falls off, but immediately gets back onto the screen and disappears off the top of the screen.
After the credits, Peach, along with the rest of the Tank Gang are still in filthy plastic bags. They have floated to the outside of the Marine Life Institute. They are then taken into the institute by some employees, much like Dory earlier in the film.
- Like Dory, Peach is able to read English as she was reading the manual on the AquaScum 2003.
- Peach was bought from eBay, however, buying live animals on eBay is prohibited. It is possible that this particular sale was overlooked by the eBay redactors, as sometimes happens.
- Peach appears to have eyes and a mouth, though starfish do not have faces like vertebrate animals.
