The 3rd level's instruction said the saw can be deactivated. I can't find a way to deactivate it and I saw some assets are outside of the background so I made this guess. If I was wrong and there is a way to beat it please tell me. Do you want a screen shot by the way?
Go from down side 1st defeat bee then defeat rino and go ahead and jump on button then saw will turn off and portal appears go through spawn point,and if you don't jump on button and go ahead in last then press jum button this is the secret ending and there is a special message.
