Marsh Lands IV

This level is to be beaten without inertia tricks or things like that.
Also special thanks to @Block builder, @chemi, and @Wang Hung for helping me test it!

Very nice level. I really like the puzzle. It took me a while to figure it out.

@Star Penguin ..... i can release pillarbot and then get him into the water but cant get him back out of that corner. Am i on the right track?

@ridgerunner Where are you putting pillarR? Do you mean the metal corner?

@Star Penguin ..no the stone corner with fencing

@ridgerunner Whoops, yes I meant the stone corner. Lol there is no metal corner.

Spoiler

PillarR isn't supposed to be in the water there.

@Star Penguin ..i managed to get pillarR out of there by a fluke.

Spoiler

then got top ball pushed into hole and knocked other ball into ditch by mistake. I am going round in circles getting nowhere!

@ridgerunner

Spoiler

PillarR is supposed to cross over the stone archways and end up close to the top ball, although he isn't able to push it. Not sure what you are doing to get PillarR into the water there.

@Star Penguin

Spoiler

was sending zapperbot in there and timing pillarbot's turn so he stepped onto him

@ridgerunner Ah I see.

Spoiler

Let pillarR cross to the other side over zapR, instead of falling down.

This is getting frustrating.
I can't get zapR across the bridge (does he even need to cross it?)
I have no idea how to even start on this lvl.

Spoiler

Not sure if I solved right... The top ball was pushed by B and ToA. I finished by B across the river with pillar R.

@TR O No tricks in this level.

what does the top ball used for?I passed the level,but didn't use the top ball.I used no trick.
