First go just over water. You come to a little cave. Just go straight pass the cave. Go up and right and you should see a blue switch. Press it and go quickly to water, wher's now opened a way to teleport. Get the key from upper part of cave, where the teleport takes you. Go quickly back to teleport, before the blue bricks move back and block you. After that go back to little cave. You see a hedgehog "guarding" another teleport. Go to it, and you fall to a cloud. Jump from cloud to cloud to left and... level completed.
