Possibly arcane beans
Spare Key: The owner of Lon Lon ranch lost his key to the front door, but he of course has a spare key for just this situation. Unfortunately, they keep the spare key in the locked house and therefore cannot get their key to get into the house. Link must shrink down to Minish size and then enter the ranch house and rescue the ill-placed spare key. Returning the key to the ranch owner secures Link a passage to lake Hylia and opens up milk sales in the city.
We got beans for sale! Big barrel of beans bursting with benefits! Some of these beans are magic, some of these beans are drought-resistant, some of these beans are heirloom quality. Come, trade for a scoop of beans, and find out what fate has in store for you.
----------
Free idea for a ridiculous vendor: A magic bean peddler that is unenthusiastically part of a magic beans multi-level marketing scheme. They try to sell you magic beans, but forgot what each of the magic beans do. After a few purchases, if they ever make a sale, they are visibly dominated by the spirit of the bean-selling scheme and make a hollow and lifeless plea for you to join their up-and-coming opportunity in selling beans.
This is actually the sort of stuff that makes it into my games. Which is why I need an item card to represent non-magical beans, just in case my party has bad luck.
