Hello everyone. I am trying to create a Nostalgic Priggle. I created two of the toys through Vanya, but I don't know how to actually change the color of my pet. Any help would be greatly appreciated.

So now that you've made the toy, you need to buy one of these:

Make sure that the pet you want to change into Nostalgic is your active one, and then bring the Essence and the toy back to Vanya's Workshop. It's been a while since I've made a Nostalgic pet, but I believe you'll be asked to confirm your choice, and that should do it :)

Thanks!
