Go through to the next area by opening your paths with the blue buttons. On the other side, SMASH! the pipe entrance. Don't go through. Go to the left and find the statue by SMASH!ing the boxes. Take the statue back to the pedestal. That'll open the path to the second battle. Cross the battlefield.
Hit the blue button - that will open the blue wall at the pedestal - and go through the other pipe to pick up the chest on the other side.
Go back through the pipe, where the blue button is. Make sure, the block next to it is UP. Cross the battlefield and go to the area where you moved the block around. The wall around the second pipe should be down now. Go through it.
Next we go right. You need the yellow labyrinth to cross to the right. Then move the block onto the blue square. Go around the little island (the walkway appears from nowhere as you go along) to get to the chest.
Also at the far center back of this labyrinth there are a couple of blocks to SMASH! When you did, you'll see that you can move one block so the door opens. Walk inside and go over the gap. A walkway will appear so you can cross to the other side and take the pipe up. Now you can get the statue off the appearing walls. Take it back to the pedestal and go get chest 1 of 2.
