They are an ultra-rare, and if you jump you even fly for a bit, along with the fact that it makes you jump very high. So if I was able to rate them, I'd say a mixture of an ultra-rare an legendary.

I have a griffin propeller what will your friend trade for it?

Idk they are from gifts and not really wanted but the rarity is pretty high so i’d say some other ultra rare item

Ok I'm looking for scooters

It is very rare for now!!!!!!!!!!!!

I have a Griffin Propeller any offers?

Uhhhhhh a dingo which will be rare soon cause it will be dino eggs

Idk the value,probably neon pet/old food/vehicle/toy

Is it worth a legendary? If it is will anyone offer me one?
