The Webkinz Adoption Center is where new Webkinz users can create an account, or where existing users can adopt additional pets. Users entering the Adoption Center interact with the Webkinz character Ms. Birdy, who runs the Center. Ms. Birdy takes codes associated with real-life plush toys and registers them to an in-game pet.
Users who enter the Adoption Center with a Secret Code or a Pet Code on hand talk to Ms. Birdy, who registers the code and gives the user a pet and an account. Users who don't have a code can purchase one from Ms. Birdy with real-life money or create a free account. Free accounts have access to limited adoption privileges. As of 2015, free accounts can adopt nine different pets from the Adoption Center, including the Cotton Top Tamarin, Afghan Hound, Pink Zebra, Ice Fawn or Floppy Eared Bunny.
After a user brings home a pet from the Adoption Center, he receives an adoption kit that contains a printable adoption certificate and pet biography. The kit also includes a unique pet-specific item and a series of gifts and currency that vary depending on how many adoptions the user has completed. Users who have adopted many pets earn more in-game currency per adoption than users who have adopted few pets do.
