Elemental: Level 4 - Anybody Playing?

Alright, Darris! You win! You already have me stumped in level four of your demo for Elemental. What I'm wondering is, is there anybody here who has downloaded the demo and taken a look at level four? I get up to the point where I use the rain element on the river, have four robots drown themselves in the river and then I run out of mushrooms.

I can't, for the life of me, figure out how to get the river wet and save a mushroom at the same time. I end up with four robots left. I have to cross one of their paths. That's why I'm asking for help!!!!!!!! Anybody got a simpler solution in saving at least one mushroom in level four of Elemental? <img border="0" title="" alt="[Confused]" src="confused.gif" />

Yes, got it!! Without looking at the hints! Now I just have to figure out level five...and I'll have solved all eight levels.

First moves (Get the mushrooms)-
Blast the wall next to you, and blast a hole right in front of the bot
Go up and around into the bot's line of sight- it'll fall into the hole.
Theres a one space gap between the bottom stone wall and the hedge..stand there. blast a hole to your right, and then blast the wall below you
Move down and under the hole..bot will fall into hole and you will get a mushroom
move down and get second mushroom
blast hole to your right again
move down and right under hole. Bot will fall leaving you with one mushroom and a clear path to the river..
