Just like the other types of Webkinz, Webkinz Signature also come with a code that can be used to adopt them in Webkinz World. With the adoption, members will get a Wish Token, an "eStore-quality pet specific item", and an exclusive item from the new Signature Theme.

The Signature Pets are released at a rate of one per month. They are both more detailed and realistic than the Webkinz and Lil Kinz pets and also have limited availability.
