In my pretend game, there will be a bear shop. items sold would be cheap items you'd be able to find in the woods, like acorns, berries, wood, honey, and fish, etc., and sometimes there's a rare chance of bear-themed armor and weapons being sold.
Little bears will play music for you while you peruse their wares to entice you to buy things.
The longer you say in the shop, the more frantic and intense the bears will play. The longer you're in the shop without buying things, little bears will come out and dance for you, goading you to buy things.

If you haven't bought anything when the music stops, the bears will throw you out of the shop. (lol)
If you return, the music will be less engaged and lazily played, and no bears will come out to dance for you, also the shopkeep squints at you suspiciously.

If you haven't bought anything by the time the music stops the second time, the bears throw you out again, and if you return after that, no music will be played for you, and the prices of the items being sold will double.
