Dust Bunny
Go to the  Dawn-Dusk Apartments . When you exit the room where you came from, immediately take the stairs and continue until you see more doors. Take the third one and go downstairs. Go down, left, down and right. Interact with the robot.

Vampirism
Go to the Cuckoo Clock World. Go right and up, then enter the clock with a door. Interact with the cat. Follow the path that'll take you to a village. Go left and talk to the NPC, who will ask you for a key that can be found by taking the other path at the south. When you find it, bring it to the same NPC; the last house is now accessible. Enter it and take the other door. In the new area, interact with the boy.

Tuning Fork
Go to the Aquarium and take the door at the north-east. Once you're underwater, find the southern path, then take the door. Go downstairs and enter the door at the right. Go downstairs again and interact with the Tunning Fork.

Mobile Phone

 * You need the Vampirism effect first

Go in the  Sand brick town , take the path east, cross the wooden bridge and enter the double doors. Equip the Vampirism effect, then talk with the clerk; he will ask you for three blood drips - to collect them, you just need to kill three NPCs. Once you've collected them, return to the shop and talk to him again.

After that, you'll be teleported to another location. Go south, west, north, east and interact with the silhouette. Go east and interact with the second silhouette. Interact with the mobile phone on the ground.

The Chase
In the Town, go east, take the wooden bridge, go south until you cross a third bridge and east again. Enter the house. Interact two times with the cog and enter the door. Try to talk to the NPC. The event starts once they've ran away ; you'll need to search for them, first in the Town. They'll escape in the Nexus, then go to the Cuckoo Clock world, to finally end their flight in the Utility Poles world, where they'll give you 100H before disappearing.

A Bright World

 * You need the Tuning Fork effect to perform this event.

Still in Town, go south, west, then enter the house; you'll find yourself on a dark world. Equip the Tuning Fork, start searching for black spheres and interact with them. Once they've all been lit, the screen will get brighter, forcing Irving to wake up.

Behind the Barrier

 * You need the Tuning Fork effect to perform this event.

Follow the directions to get the Tuning Fork effect, but instead of going south in the underwater area, find the western path. Enter the double doors, equip the Tuning Fork and interact with the box that prevents you to go any further, then catch the NPC ; he will give you 20H.
