This world is accessed via the Grandfather Clock. To travel over the ledges into the water, the Snow Bug must be used. Usotsuki can freely walk in the water by herself once the ledge is crossed, however.
A strange NPC with an eye on its back sitting next to a set of scales provides the Chimera effect. If Usotsuki interacts with it further, she will back away, a reaction unique to it.
A floating creature drifting through the murky water will take Usotsuki to the Red Bubbles Maze.
