Brief description: A variety of treats can be placed in each ball of paper, making the surprise of what is inside each paper ball even more fun. Some paper balls can be left empty, encouraging the chimpanzees to keep looking, and making it more difficult to find all the treats. The paper balls can be spread around the enclosure.
Materials: Kraft paper, dried fruit, seeds, nuts in shell, peanut butter
Assembly instructions: No assembly required.
How to use: Cut or tear ~ 12″x12″ sections of kraft paper. Place treats in the middle, then crumple the paper around them. If making empty paper balls, cut or tear a larger section of paper so that it is not obvious the ball is empty.
Price: ~$20 for a roll of Kraft paper, which lasts a long time.
