After you have planted the beans in the clover patch, a massive bean stalk will sprout and grow into the clouds. Before climbing the bean stalk, check to see you have these items for what's to come:
- The magic ring given to you by the Elf (located in E8).
- Some small rocks (located in A6).
Click as an action on it to begin your climb. And I would recommend saving at this point as the bean stalk is not easy to climb.
