Once in a while someone will have the mats (account bound) and make a post.. it’s pretty rare. The person opening needs ALL the mats. It doesn’t happen enough to really be a thing.. and the drops are okay, but even just a Prankster Goblin gives you much more and those are only 80fg atm.
The experience is kinda cool though.. but by the time you do it or coordinate with someone you are already most likely over powered for it
