I just want to trade up.

The steps are very simple, don`t let the other answer let you down because it is real.If you used to be a member then you`re in luck. First go under water (I use Crystal reef).Then, recycle all of your land animals DO NOT RECYCLE YOUR FOX!!
Next,do not use the map but go on land such as Crystal Sands.There you go,I have not gone through the steps because I have Membership.But I hope it works for you.
