Go to the dungeon and use a permalocker(a tall machine) when you had all of the maid/pony equipment on. But how to go to the stable? I don't know.
Witch tall machine? there are a few of them but one type doesn't seem to be working.
go to the editor. It's on the right of the big crate
OK I tried using them in the field but they are not even giving a prompt
it only works when u ra wearing a whole set. pony set has 4 pieces,maid set,5
