What happens on animal jam if you don't pay the money for the membership?

Well you can buy another webkinz and put it to your account by using the button adopt another pet on the log in page. This will give you two more months to have a full webkinz membership. If you prefer to not get another webkinz, your expiring webkinz doesn't expire completely. You can still play but you have limited choices of what you can do on it. For instance, you won't be able to use party packs. Deluxe membership can be found on the log in pace, too. Hoped this help.
