How does the Mad Hatter live on Batman Akam's side mission?

After coming out of the sewer of the police station, you will meet three guys who sing and welcome Batman to their carnival party. They were the puppets of the mad hatter and were executed after singing. Later, the girl Alice's cry for help came from the communication channel, and Jarvis, the mad hat dealer, greeted Batman and said that he had a job to consult.

Such as Alice in Wonderland, colorful fairy tales. There is a circuit board on the bridge deck. Don't go until the current disappears. The end of the bridge will run to the last circuit board and hit the lampshades on both sides of the keyhole with darts. When they are all destroyed, the suspension bridge will be put down.

Climb along the vine-covered stone wall and jump from the hole in the wall to the corridor at the bottom of the tower. Three doors correspond to the mirror above, and a person wearing a rabbit mask will appear in one mirror. If you enter the wrong door, the mad hat will laugh. You can get out of the maze by constantly entering the door under the rabbit mask.
