There will be one fuse in the panel. You will see that, depending on where you put the fuse, one of the lights will turn on. These lights represent which metal door is open, and they are in the same spots as are doors on the floor plan. You will find more fuses later, which will allow you to open more doors simultaneously. Place the fuse in the position like in the picture above.

From the starting area of the hallway, go forward, and then left (you will see the closed door since you haven’t opened it yet).

In this game, use the arrow buttons to jump on trains or to jump over obstacles. The longer you run, the more score you will earn.

Try to collect the coins to improve your score.

Jump over obstacles. If you hit the obstacle once, the corrupted soul will get closer to you, but if you hit the obstacle again while the corrupted soul is close, it will be game over.

If you collect the white cube, you will be teleported to a different area.

After the white cube, you will play as Harvey, but in the pure bird form. In this area, you can collect a lot of coins, but you’ll need to press the Up button often to avoid falling into the lake. Once you hit the lake, you will return to the main section of the mini-game. There is no special reward for this mini-game. You can try to have the greatest score among all the players if you wish.
This will mark the end of our guide for the bonus content of the Underground Blossom.
