World 3 - Level 8
Use Qookie to push boxes along yellow arrows, then open the purple door. Use Stinky to move the box along the red arrow, and collect the bonus coins behind the fake wall. Stay at the red "X". Now move Loof into the room and to the purple "X". Switch back to Qookie and push boxes along blue arrows. Now three boxes are available to be placed on the three buttons. Collect coins and exit.
