BINA,
That combination of Kabooms and Zbots is tricky..and it is a matter of timing and standing in the right place.
Here is how I did it:
SPOILER
Start the set-up as soon as you get to the first box as you walk behind the Kabooms....quickly
One box goes on the top left to block that Isle, the other 2 go on the right side by side. As the Kabooms come around they will explode way over on the left when they walk up that narrow isle. You will be left with one.
Now, on the right side, move the outside box down S past the opening and the top box even with the opening. This is the pattern you want to end up with.

Run in and move the box that is in with the zbots, left 2 spaces. You want to create a trap. Push the top box up so you can get out, and then back down into place. Now when the Kaboom comes around and into the room, use the top box, shove it in there from the right and it will explode. Now stand still...as the Zbots will all fly out and collect at the top area. If you stand in the path where you pushed your box in, you will be safe. You won't need to go out of the room again, but now you have to bring the other guy in from the bottom.
You may have to do this a couple times to see how it works, but when you get it, you will be so happy!
