How do you get along with the remains of underground mushrooms?

1. In an area near the waterfall in the game, there is a place to order mushrooms, which is divided into two ways.

2. On the way down the branch, the mushroom always points to the end.

3. Then order a mushroom on the way to the right branch, and then go back to the way to the downward branch. At this time, there will be a downward road outside the map, and you can open the mushroom door when you walk in. There are still mushrooms under it, and this piece will pass.
