You find yourself in a strange candy store. Move to the Chewing Gum Dispenser (on the left) and press the red button. The machine will produce a Chewing Gum. Get it and use it in the inventory obtaining the Chewed Gum. Examine the Shelf to the left of the large machine and move it. Plug it in - Cotton Candy Machine works now. Move to the right, to the Anchovy Machine and press the button. You'll receive Anchovies on a Stick. Open the inventory and eat it, obtaining the Stick. Move to the cotton candy machine. A Lever to the left is responsible for the type of cotton candy - move it to Phosphor. Use the Stick on the machine obtaining Phosphor Cotton Candy (Notice - if you have used the stick on another type of the cotton candy, it is not a problem. Just eat it and try again). Go to the left - to the lobby. Head to the tower. Unfortunately there is nothing interesting to do here right now, but notice the Barrel with Water in the bottom right corner. Return to the lobby.
Go to the concourse. Pick up Mosaic Stone from the ground.
Continue to the right until you see a Dirty Mosaic Table. Bit later you'll find Pebbles on the ground - take one. Use the Phosphor Cotton Candy on the Lamp - you'll obtain Glowing Phosphor Cotton Candy. You can put in the Hatch under the left mosaic to see what it shows.
