There are so many characters in all of the animal crossing games. Even characters that are always on your island, like the staff, Timmy and Tommy, (the twins) Tom Nook (the main guy) and Isabelle. Tom Nook adopted these abandoned twins Timmy and Tommy, the tanuki’s just like himself. Isabelle is a dog and there is a museum guy named Blathers and he owns the museum. You can have up to ten villagers and up to four lpayers on the island.
