How about a new toy to play with, but one you can make on your own? You can activate a potato with some hot pepper to make a "Hot Potato." This Hot Potato is so very hot, you can't hold onto it for very long, or else it'll explode into a ball of tuber-y flames! If the blast happens in your hands, the items in your inventory will be rearranged. On the up side, the people around you will gain some mood at your expense.
Possible variations on the idea:
-different existing item? hot mangosteen, pumpkin, dice, etc.
-new unmakeable item? "passing the duck" or "musical bears" with stuffed animal style toys that don't explode, but might honk or growl at you or look at you disapprovingly
-different outcome? lose energy, gain potato seeds, can't pick up anything due to scalded hands, etc.
Thoughts?
