Aywas

"Aywas is a collectible pet site for older teens and adults. Adopt as many pets as you want, and explore the seven regions of Ay for wild pets to capture and add to your collection. We are a submission-based virtual pet website, so you can color pets, create items, and create Human Avatar clothes for everyone else to enjoy. We offer battling, breeding, mini-games, an active forum, and the ability to create your own custom aywas. Color the adoptable bases, and even edit them to look more like your characters. The possibilities are endless!"
