Didn't work out for me the first time, but got a thrill when it worked the second time. Thank you for such a cute and fun level!
@TR O Spoiler When you get R down of the building, Make B get zapped and fell into the hole to gave R a "Body Bridge". Hope that helped
Took me a while to figure it out, but I finally got it. Spoiler Definitely need to watch your timing at the end - for a few tries, I had B fall anywhere but where he was supposed to
@chemi @Ricko and anyone else looking for a humane way to complete this level: Spoiler: Humane Solution (hint on previous page of comments) The hint was to give R a little push. The push needs to come from the curved rail portion of the higher draggable. In other words, once you have R down by the moving zapper, keep B clear of that side and simply drop the rail down on R when he is mostly on the block by the hole in the ground. I say "mostly" because he also needs to be partially on the block below the rail in order to be squeezed by it towards the win block. Thanks @chemi for bringing my attention back to my incomplete promise!
I really dislike having to sacrifice B. I will put a lot of effort into avoiding that outcome. I solved the level using the method @nGord described. That did take several tries and once sent R into a somersault which apparently scrambled his circus and he started doing somersaults in the open space and then he finally bloated often to the distance, where is in the garbage collector got him and he went to the great big bit bucket in the sky.
