The Prize Claw is a furniture item granted when the player reaches level 162. When clicking on the item, the prize claw starts working and tries to grip a green plushy which eventually slips out of the claw. No matter how many times you click the prize claw, the plushy will always slip out of the claw.
Before the levels were extended from 200 to 500 in March 2016, this item was one of the random items that came out of a Diamond Mystery Box rewarded from level 51 to 150. Because of that, there are Prize Claws that can be traded and gifted.
