Is it just randomly given out while playing or while sending score? Do you have to get a certain amount of points?

Randomly when sending score IIRC. No clear idea on point value. Good luck!

: Oh my, this beanbag was my nemesis for YEARS!! I tried all kind of scores/ point values etc. It truly seems to be just random but a rare drop. I literally tried for years and then got two in a week. Keep trying, you'll get it eventually. Good luck! <3
