Check out our yo yo animals selection for the very best in unique or custom, handmade pieces from our patterns shops. A 12″ tall yo-yo bunny whose body is created with two sizes of yo-yos strung together with thick thread and attached to a stuffed head with floppy ears. As part of our commitment to a sustainable future, Henry Vilas Zoo is celebrating this Save Our Sea Ice Day by starting installation of a new roof on our Tropical Aviary Building. The new panels will greatly increase the insulation values helping us to reduce our carbon footprint. We anticipate the construction will be complete in August.
