Hi ddb,
I bring you (as promised) some help.
----------------BIG SPOILER-------------------
Push the box with the yellow arrow 2 squares up. Dump the purple marked box in the lava, and build a bridge at the yellow X's. Do not move the yellow marked box. Place Stinky in safety just below the yellow marked box. Switch to Loof and stand on the first part of the bridge untill all z-bots are destroyed. Run to the purple X, wait for the shots to pass. Now you can safely collect the upper coins. To make the return trip safe, push the reflectors as shown with the purple arrows. Get the coins at the bottom and enter the TP with both Loof and Stinky.
Place one of them on the yellow button and make the other one push the boxes into the lava as shown. The box with the light blue X is a bit tricky, since you have to push it right, wait for it to turn and then follow it onto the ice. When the bridge is done, stand on the green button.
The other character can now build a bridge over the lava from the other side and place boxes on all the buttons including the green and yellow ones.
To get the last bonus coins, you have to wait for the Kaboom! to be in the position shown, then quickly follow the white path and watch the Kaboom! get electroed.
----------------END SPOILER-------------------
Thank you very much for playing my levels

I hope this helps you out
Mette
