The cubs can't get out of the hole that protects the novice's home.

You create a dragon to break the shell and become a cub. When you finish eating and drinking, you need to hand in the mushroom. You take the mushroom to the hand in point, and then put it there next to the upper corner point, which is not the upper intersection point. Then you pick it up and hand it in again. You don't get the reward, you quit directly. Then re-enter, you will find that you can't get out of the cloud hole, and the growth value is not enough.
