How to AdoptEdit
It is fairly easy to adopt a new pet. On the Login page, you just type in your username and password and click "Adopt a new pet" Instead of "Begin Playing". Then Mrs. Birdy will go through all the steps with you.
If You Are Already in Webkinz WorldEdit
If you are already in Webkinz world and you don't want to have to log out, you just go to Things to Do, and It'll be under the list.
Mrs. Birdy will greet you, and then ask you to name your pet and let them know if it's a boy or girl. The next step has you enter your secret code that you received with your plush pet. The next screen is a verification screen, when you have to retype some letters in a box. That's it!
