Rubber Ball, like Deck of Cards, serves no purpose other than amusement. It can be bounced on empty ground. To craft, use a Clay Bowl on a Bucket of Rubber Dough, then fire the Bowl with Raw Rubber Ball in a Hot Adobe Oven to get Bowl with Vulcanized Rubber Ball. Attempting to place the bowl on empty ground will remove the Rubber Ball.
- Uniquely, babies can pick up and play with Rubber Balls.
- Rubber ball can be used to erase words from notes and return them to blank paper. Cannot be used to erase the word 'Peace'.
