Puru bubbles

Help the colored geezer to get off the blocks and get to the exit. The only problem is that they do not move themselves are. And you can move them, but if you clean up the blocks, so that they fell into the portal. Do everything carefully and take your time, because they can drop by or even the other way. Importantly, make sure that geezer did not fall to the floor, because the climb up, then do not come out.
