How do you do level 18 on small fry by nitrome

Send the Sporty to the right across the water. Do not hit the button in the water. Have him crawl up and past where the bridge will soon be.
When he stops at the blue platform, send the skeleton the same way but drop him onto the button (drop him right over it.) Now the bridge will be made. Leave the skeleton in that area because you will need him later.
Turn the Sporty around so he is facing left. Then drag him off the platform and let him jump. The bridge will make him fall through the hole. When he falls, he will try to crawl up again. Make sure you grab him before he walks into the no-click zone! Drag him into the next hole and he will begin to walk to his left. Then he will crawl up and press the button which will activate one of the doors to the exit.
Turn the Brain around by dragging him almost to the edge of the water. He will turn around himself to face the left. Then, drag him off the platform so he falls into the hole. Once he hits the bottom he will turn around. After he does that, he will land on a hill sloping up to the right. Wait for him, he will turn around once he sees the edge. He will then walk down the hill and activate a flower which will open a door to another button. This button will open the last door to the exit.
Grab the skeleton when he is out of the water and facing left. Drag him onto the platform to the left and right before the no-click zone, let go of him. He will fall down the hole. When he falls again, he will hit the hill and start walking up. Let him do this and let him walk off the cliff with the spikes. (He cannot die.) Once he hits the spikes, drag him up and to the right until you hit the no-click zone. Drop him there and let him walk down the hill. Once he hits the button, the door is open and the Brain can exit!
