Somewhere on the edge of Wondertown...


Hint: You need one box each to exit, and keep off the green.

Full Solution:


Have Stinky push the box below down 1 square.
Go back to the red button and push the left box 1 square left.
Walk back round to the yellow button and collect the bonus coins in the hedge.
Walk round to the pink and blue buttons collecting coins as you go.
Push the box below you down and onto the green button.
Walk back to the top and push the top box onto the blue button.
Walk all the way back round to the red button and push the box to your right out, then walk back round and push it up and past the pink button, then walk around it and push it back onto the pink button.
Push the box below you to the other side of the red button, then walk around and push it up onto the red button.
Push the box at the bottom onto the yellow button.
You now have one box each to make a bridge. Roll boulders onto spikes to clear path.
