How to enter the Misty Swamp in Moore Manor

First go to the thousand-year-old banyan tree crown on the map of the black forest to find the hen. Click on the bugs that keep jumping out based on the color of bugs you want on top of its head, and then give it to the hen. It takes you there. In the meantime, I want to play a very simple game, which is easy to control with the left button. Just hold down the left button and avoid hitting eagles, trees, and thorns. After playing it once, you can reach it directly if you enter again in the future.
