On my second trip through the levels I finally realized that I had entirely missed the most simple solution to level 42, Scattered. I was concerned about getting T Rex out of the way so Matthius could slip by to his right Goal. Do it this way; first move Skimlet one square to the right and immediately back again. This looses a single wave of spores that attract T Rex one square to the left and keep him out of the way forever. The next important thing is to have Matthius trip the lower left switch. Keep one Rightie alive long enough to trip switches to move Howard to the upper left switch, opening the way for Matthius. Matthius can then remove the remaining rightie, to keep him from tripping any more switches, and go home to the right goal. Howard can grow a tree and move on to the upper left goal, and Skimlet can move right to his goal.
