I changed my pet Mr.Miyagi into a Nostalgic Neela by mistake. (I thought the change pet button would give me the chance to change my active pet) Is there a way for me to change them back? Or once they're changed that's it?

sorry about that! But no, the change is permanent. I mean, you can start over and get the potion you need to change it back, but there's no undo button or anything. And if you still want a nostalgic neela, you'll need to recreate that for the pet you actually intended to change. At best, if there's a cheap elixir you can use, its a pain, at worst, it can be pretty expensive depending on the original color.

It was actually a chibi experiment pet : ( But thanks!

oh...that hurts! Really sorry :(

I have a couple of Experimental dews I can send you way!

There was no need to, but I really do appreciate it! <3
