There are various levitation puzzles in this room to help you learn how levitation works. Construct a ramp in the back area of the room with the bricks as shown in the painting. It will take a little while to get the hang of how to do this, but keep practicing, you're going to be doing this a lot. The key is to be patient. Go up and hit the painting, and save the boy. Then make the legos into a #1 sign to get the coins. You get gold brick 8/200 for saving the boy on the right. You build the pink statue including the spear. You get a "boy" unlock.

Make sure you smash and play with everything in this room before you leave!

Back in the hallway, levitate down the ball for the kid, you get a Student in Peril bonus. Return back into the main room.

Arrange the books into the bookshelf, then knock them out a few times for coins. Save the boy by the bookshelf by building the books into a ladder. Build the pillar by the central gates, making it match the picture on the wall. This will open the gates. Turn the smashed statues into silver statues by levitating them. Light the torches.

Go up to the lion and by feeding him you get a secret door to open behind him. Go down that hallway and then left into a big courtyard. Explore in here. There are things here you can't do yet - don't worry about it. The game unlocks over time. Once you're done playing, go back into the main room with the torches and statues. Go through the central door.

Now you're in the upper level of the stair room. Smash and levitate everything. Don't worry about the gold cauldron, you can't use it yet. When you're all ready, go into the doorway.
