The Underwater Amusement Park is a very large area accessible from the road in Atlantis.
Features
The entrance to the area has hexagonal ticket booths, pink neon columns and purple smiley faces on the floor with a few children walking around. If you interact with the balloons, you buy them and they hover over your head. There is also a column with letters scrolling up it that can transport you to a scene where child Urotsuki is standing alone with a spotlight on her
while shadow people walk past her, however the text must read "さようなら" (Sayonara) when you interact with it. When you go into the amusement park, it has a number of different rooms with varying floor tiles, monsters and
music.
- If you go to the area with the purple wavy lines, you can find a cowboy riding on an old TV. Interacting with this gives you a new wallpaper.
- If you go to the brown eye area and go up to the stage, the cycloptic pyramids will perform a dance for you. You can jump to the stage using the Spring effect. Theres also a chance that after watching the dance of the cycloptic pyramids, an upside down goat head appears in the same area. Interacting with it will cause a full screen event to occur.
- In the area with the pink faces on the floor, there are a number of TV screens that transport you to different places. One of them (from brown eye area's upper entrance, go down to the third one) can transport you to a TV shaped room with white smiling faces on the floor. Going down and entering the door will lead you to a zigzagging path that takes you to a room with many TV screens. Interacting with them will make animations appear on them.
- There is an entrance to a water ride here where Urotsuki can ride in a boat with an eye on it. There is also an area where you can ride to the Train Tracks on the eye boat.
The area with black and teal checkered tiles leads to the dungeon. By interacting with the turtles with keyboards on their backs, you can make piano-key bridges. As you proceed, you can see the Clown Triplets and several children. Go into the building with the big clown on it to enter the dungeon.
The dungeon contains several children locked up in cages. If you go down the stairs, you can see single cages with statues
of other chasers on top of them. On the last floor, there are many open cages with bones in them, obviously suggesting that the children have been killed by the clowns. When you exit, there is a room with two doors, showing boy and girl symbols on them. It doesn't matter which one you choose to go in. Urotsuki will still suffer the same fate.
She will fall down onto a hexagonal platform, unable to get off it. Two children on similar platforms will appear next to you. Large columns will come down and squash them, revealing prints of them now on the platforms. After you go through the same unfortunate process, you will wake up.
