How do you beat level 20 on meeblings on wwwcoolmath4kidscom?

First click on the green meebling to make it turn into a tree so the meeblings will not be sucked into the red fan. Second, slowly click on the yellow meebling that is in the small ditch to cause the pile of meeblings in the top left hand corner of the screen to fall through the hole. Keep clicking until all of the meeblings from the pile make it to the "WAY OUT" sign.

There you go!
