I've seen some pets with HAs on their profiles. Does anyone know how to do that?

You can create an HA in the wardrobe then screenshot the HA. Atleast that's what I think they do.

Like Malevolence said, you can create a ha in the wardrobe and then take a screenshot of it. Or you can use a generator like the one at arvee, save and then upload that. c:

Thank you!
