The Tower of Beatrice

Here's the full solution to Room #4.

• Take Shard #1 in front of the giant snowball.
• Zoom in to the table on the right. Take Shard #2.
• Zoom in on the diamond on the wall. Take Gold Medal.
• In this exact order, set the left shape to green. Set the top shape to yellow. Set the right shape to dark blue. The shapes will disappear. and you'll be able to take the Triangle.

It's possible that these colours are different in different playthroughs.

• Interact with the ammonite fossil, and then zoom in on the chest to the right of where the ammonite fossil was. Take Shard #3.
• Zoom in on the mirror and place the triangle and all three shards onto the mirror.
• Zoom into the chest where Shard #3 was, and set it so the gaps in the lights are as follows:
- Top left symbol - Gap is at top right
- Top right symbol - Gap is at top right.
- Bottom left symbol - Gap is at top left.
- Bottom right symbol - Gap is at bottom right.
• You'll get a message from Beatrice. Click each symbol three times and then unlock the chest.
• Zoom out, then zoom back into the chest.
• Take the Shard #4, Magnifying Glass, Firefly Lantern, and then use the Firefly Lantern to capture Firefly 1/9 and Firefly 2/9.
• Zoom out and use the Firefly Lantern to capture Firefly 3/9 and Firefly 4/9.
• Zoom into the diamond and use the Firefly Lantern to capture Firefly 5/9.
• Zoom into the mirror and use the Firefly Lantern to capture Firefly 6/9. Also use Shard #4 on the mirror.
• Zoom into the desk on the right and use the Firefly Lantern to capture Firefly 7/9.
• Use the magnifying Glass on the small pink glowing circle near the ammonyte fossil, and then pickup both Magnifying Glass and Ammonite Fossil.
• Zoom in on the diamond, then use the magnifying glass on the tower at the top right.
• Take the second Ammonite Fossil, and then speak to the spider. She'll give you a Cloak. Also, if you speak to the spider again, you'll see a certain reference...
• Zoom into the table on the right, and use the hankerchief/cloak on the hole in the pipe with the steam coming out of it.
• If you look in Beatrice (the book), we're wanting a 'Through the Mirror' Potion, which requires 1 piece of Gold, a Magna Maximyz, and a Sea Creature House. Now the steam is no longer escaping, we can click on the trapped items inside the experiment.
• Change the first item to the plant with a purple head (A thistle?)
• Set the second item to the plant with a blue dot on each of the four leaves.
• Set the third item to a buttercup (yellow plant with five petals).
• Set the fourth item to the greyish 'root' thing.
• You'll then be able to open up the bottom container, and take the Plant.
• Zoom out, and in this exact order, use the gold medal, the first ammonite, the plant, and then the green bottle in your cauldron. You'll get a potion.
• Use the potion on the broken mirror (you'll have to attempt this a couple of times).
• Zoom out, and capture Firefly 8/9 and Firefly 9/9 with the Firefly Lantern.
• Use the Firefly Lantern on the dark place to the left.
• Interact with the skull to take a Gold Tooth. Keep talking to the demon until a teacup appears.
You may need to zoom out and then back in to talk to him again for this to happen.
• Zoom back into the experimentation desk, and set the four items to Raspberry, 5 Green Leaves, White Flower, and the thing that looks like a tree with no leaves. Take the Raspberries from the bottom container.
• Give the raspberries to the tea-summoning demon.

Achievement Unlocked:

• Take the hankerchief/cloak from the pipe with the steam.
• Use the magnifying glass on the magic circle, and then use the hankerchief/cloak on the circle to make it grow in size. Take both magnifying glass and the blanket.
• Give the blanket to the demon, talk to him, take the blanket off of him, talk to him, give the blanket back to him, zoom out, and then talk to the snowman until he moves. Take the blanket back off of the demon.
• Take the Sledgehammer from behind the snowman.
• Zoom in on the door. Arrange the four symbols in the following order: leaves, flower petals, fruit, roots.
• You can now open the door, but can't escape because of the ice there.
• Use the sledgehammer on the ice twice. Click on the ice and you'll get an Ice Shard.
• Use the ice shard on the mirror.
• Use the blanket and the magnifying glass on the circle. Pick up the hankerchief/blanket.
• Go back to the experimentation table.
• Change the four items to the Thistle, the leaves with blue dots, the buttercup, and the greyish root thing. Take the Buttercup Plant.
• Use the gold tooth, buttercup plant, and the second ammonite on your cauldron, then use the bottle on the cauldron to get a potion.
• Use the potion on the mirror next to the demon.
• Take the Shard from the small mirror.
• Use that shard on the big mirror.
• Interact with the glowing mirror to complete the room.
