Nothing happens; doesn’t affect the game.
The player can access the inside of the machine, manipulating the prizes from within by moving around, allowing the actual player (i.e the player that is moving the crane) to obtain more than one prize. The player inside can also glitch the claw.
I’ve redacted the method to get inside, in order to prevent exploitation of the bug.
If developers would like to know, please PM me.
