In all my time on this earth the only time I've seen someone, living or fictional, win something from those machines....was when Bloo won the paddle ball.
It is at this point I'd think most people would realize to not waste their money on those things.
I'm half decent at them, about half this junk is from claw machines. I prefer Namco places over Taito Station. (Don't worry its not all vocaloid, the shelf below it is all kirby) Also mostly Kaito and Len because I'm fujoshi trash.
