Balls, in Doubutsu no Mori, Animal Crossing, and Doubutsu no Mori e+, are objects scattered around the town. They can be kicked, but cannot be picked up and are difficult to control. Sometimes, the ball may fall into the river or sea or vanish when it is offscreen. To make it reappear, one must simply enter and exit a house or save and restart the game. Villagers interact with a nearby ball by either kicking or chasing it. If the player brings one to them, villagers will reward them.
There are three types of sports balls: the soccer ball, the basketball, and the volleyball. The type of ball is random.
