What do you get from the Prize D-Spenser in Mouse: P.I. For Hire?

The Prize D-Spenser in Mouse: P.I. For Hireis a locked cabinet inside the Little & Big Bar, over the road from your private investigation office. If you approach it, on-screen text explains that you need 20 prize tokens to open it and reap the rewards within. That’s a lot of tokens though, and to earn them, you must win at baseball cards, against the opponent at the other end of the bar.
