Balls

&nbsp In Animal Crossing (Gamecube), everyday there will be some sort of sports ball somewhere around the town. They can be kicked around, but can't be picked up and are difficult to control. Sometimes, the ball may fall into the river or ocean and vanish when it gets out of sight. To make it pop back up, simply enter and exit a house, or save and restart the game. When brought to a villager, they will kick it around and chase it.

What it's for.
Sometimes, a villager will ask you to bring him or her a ball to play with or train with. If you bring one to him or her, he or she'll reward you. Also, two snowballs appear every day in a town during Winter, and can be made into a snowman. The snowballs are also more delicate than regular balls, but when they become large enough, can be easily rolled around, meaning that they become easy to control.

Problems.
They are very difficult to control. If you try to bring it up a hill, it'll simply roll down until you block it from rolling. If it lands in a body of water, you'll have to let the town reset. If a snowball is hit with an axe or a shovel, it will break. It will also break if it lands in a hole or falls down a hill.
