If you can't solve it, here's a solution:
Sorry if it's long.Have Loof move the two steel boxes left and right. Push first one in your way down into the water. Then push the steel box up, the wooden box two spaces left of you up, for the Rainbow Coin, head back down, and push the wooden box to your right right into the water. Push the two boxes near the teleporter right, and push the last one up into the water. Have Loof enter the teleporter and head to the far right. Head down into the wall for a bonus coin. Come out and switch to Stinky. Head to Loof's location and up. Push the higher box right, and push the other one down. Switch to Loof and push it left until it lands in water. Position Stinky as far up as he can go. Have Loof press the conveyor timer and push the steel box down, right, up, and left to the lava patch. Press the green button. Then head back through the teleporter and all the way right. Have Stinky push the box down. Switch to Loof and push it into the teleporter, and one space from it. Push it down and right to press the blue button. Then press the conveyor timer and let Stinky through. Have Stinky push the two of the boulders left so that the purple and yellow buttons are pressed, but not the red. The final boulder should be two spaces below the red button. Then have Loof activate the timer and quickly push the before-mentioned boulder onto the red button. Then have Stinky quickly grab the Scouge-guarded Bonus Coin and place hin on one of the break tiles. Position Loof on the other. Now the way to the exit should be open.
