Moppina is an unseen mop character that normal villagers frequently refer to in conversation in Animal Crossing: Wild World, reflecting upon their reserved and shy nature. The mop is revealed to be the best friend of a normal villager, and after conversations between two normal villagers will reveal that Moppina is the friend of any normal villager in the town. When talking to other normal characters, it is revealed they both talk to it, try out hairstyles on it and even cook with it. Normal characters also talk to snooty types about Moppina, but not with as much success. When they talk to peppy villagers about Moppina, the peppy villager asks if they can meet her. Moppina is mentioned in Maple's picture in Animal Crossing: Wild World.
- Mops are available from Tom Nook's Store for 800 Bells, but they cannot be interacted with in the same way as normal villagers are believed to interact with them.
- It is widely speculated that the mops that can be bought from in-store are Moppina, but this is pure speculation.
