Climb the chain in the upper corner of the room. Interact with the hanging body.
Reaper
(The Hanging Rope or Cloud Effect is required.) Follow the directions to the Hanging Rope Effect, but go up at the fork instead. Follow the path until you reach a room with another large chain, and head left. Head left at the next fork and use the Hanging Rope or Cloud Effect to cross the gap and enter the hole. Navigate the maze to a dead-end space with a square in center. Step into the square and press Z to warp to the next area.
Continue straight ahead. At the final platform, step on the white circle. Head southwest and step inside a black hole. Follow the stone path right until the path doubles up and goes north; continue rigth and pass between two columns of gravestones nearby. Carry on north and approach the grim reaper.
Hole
Follow the directions to the Fish Effect, but instead of heading into the squat building, find and enter the building at the top with the double entrance. In the next area, search for another entryway much like the one you entered from: inside, interact with the square to be teleported to the interior of another building. Exit into the Demon Capital and go north and cross a boardwalk to a roof area. Continue up and past the trees into the Hand Settlement. Find the topmost dwelling on the right of the map and enter it. Carry on along the path. Interact with the hand-like object sticking out of the ground.

Find the topmost dwelling on the right of the map and enter it. Carry on along the path. Interact with the hand-like object sticking out of the ground.
Abstract
(The Wings Effect is highly recommended, if not required.) Follow the directions to the Fish Effect, but instead of heading into the squat building, find and enter the building at the top with the double entrance. In the next area, search for another castle-like entryway. Continue through the next few areas until you reach a barren wasteland. Walk to the other end and find a small square exit surrounded by mounds. Navigate your way through the white paths to a yellow exit. Head to the left to the edge of the purple area and locate a bridge. Carry on along the bridges and across the islands to the uppermost ridge of the map. In the next area, equip the Wings Effect and activate it to freeze the Noppera throughout the purple maze. Make your way up to an exit at the top, then interact with the purple mushroom.
Exit into the Fungi Forest and search for a multicolored mushroom. Interacting with it will warp you to a psychedelic world. Locate the checkered patch on the ground and step on it. Interact with the brilliant starburst at the end of the path.
Cloud
(The other seventeen Effects are required.) Follow the directions to the Planet Effect, but take the first staircase nearest the train instead. Use the Lab Coat Effect to enter a smaller spaceship and interact with the single lever at the front. Wait a few minutes until the craft comes to a stop. Exit south to the Cryptic Tiles Maze. Somewhere to the left is a second staircase. In the next area, you will encounter rooms which require a specific effect to successfully clear. Once you've crossed all the rooms, follow the stairs and interact with the cloud on the landing.
