I couldn't figure out a drop mechanic so i actually put in different "strengths" to the claw's grab. It can randomly pull of of 3 different sensor sizes at time of grab. One basically doesn't exist, one is tiny and one is fair sized and can sometimes grab 2 plushies. So depending how you align the plush and what sensor it pulls it has a chance of failure like a real machine but luckily since i didn't have time to figure out how to make them drop early once you've grabbed it you're golden lol.
