well if you decide on something specific let me know I would love to help! I am weird about my pets I am super random lol... my main pet (Wemay) is my dedication to my late kitty and it has a custom overlay based on Angelic Feli, the other (HeadDesk) has a custom overlay as well that is an adaptation on the Nostalgic Heiki. You can have people design overlays and pay to upload them. Those two are the ones I had planned for now to make customs. But for sure if you have a particular pet/color combo PLEASE let me know! I can help!

What pet/color combo are you thinking of?

It can depend on which pet you are looking for but there are potions for the more rare colors
