Switcheroo Zoo a.k.a. Switch Zoo started as a small project. We were playing around with the idea of making new animals by switching their parts. At first, the zoo had just nine animals, and it was the only attraction on the website. Today, there are 142 species in Switch Zoo, and the site features animal games, music performed using animal voices, a reference section about all of the animals in Switch Zoo, lesson plans, and poetry, stories and artwork created by students and visitors.
