This set consists of Zhu pawzles only and is a great addition for increasing the number of combinations on your base. Zhu is a pawzle that takes up 4 spots on the base and requires pushing the sliders to uncover the 4 treats underneath them. The sliders can be pushed with a dog's nose, tongue, or paw.

You can fill in the compartments with treats, regular dog food, or even peanut butter for your dog to find.
