You can win level 27 with only two of the climbing stones. Just place the first wait for all of the dribbles to cross and then place the second on the ledge.
I finally figured it out we arn't going 15000 meters we are suspended on ropes that we can't see and they are moving the platforms towards us. On a side note they also have a giant reel of fake backround they use to make us think they are moving.
The only problem I had is that in the third level if the sign hits one of the smaller sheep first it will push that sheep even if shirly is standing right behind them.
Some of you are saying this game is boring and repetitive but I say can you balance three turtles on top of you head and walk around? I didn't think so.
I don't know if it happens in other levels but in level 16 if you jump when pushing the block with ceiling directly overhead you can jump thru the ceiling.
