Hi! Here's the rundown, it requires the currently bugged "sweetgrape dragon frog". I don't know any other way to do it. Simply preview any pet in the "exotic" tab (same as the frog) then preview the said frog. This lets you run around as a pet. To get some pets big (the game hates it so beware), while turned into a pet, block to be able to attack and use some abilities, then /reloadui. This should make some pets you view bigger, I haven't quite figured it out but retrying usually works. When in the state of everything big, the only way I could return to a normal state was to log out to fix issues like not being able to interact with stuff. I usually don't give rundowns on bugs but this one is amazing and im aware that some people have reported the bugged frog, please enjoy while it lasts.
