The scale part. How do I get 3 of them to the buttons to open the door? The Spikey is one of them, but how do I get 2 of the regular ones over?

i am stuck on the same level. But i freed the other 2 rolandos that were stuck on a ledge using the crane, so i think getting 3 rolandos to the button shouldn't be a prob

Hint: Let no object that you can move go to waste. SPOILER!! Use the purple blocks from the crane to "balance" the left side of the scale. SPOILER!!

I got another problem in 'under construction' I have removed the two crates that were blocking 2 rolandos, but how do I get these rolandos out of the hole?
