Across the Lake


Hint: Push boxes into the red teleporter to see where they'd end up.

Full Solution:

Push a box into the red teleporter from below (!) to build a bridge connecting to the yellow teleporter. Now push the second box into the red teleporter from below (!) and further through the yellow teleporter twice (follow the yellow path). You are now on the other side of the lake.

Collect all coins by stepping onto the ice from various positions and directions. To get all the bonus coins, enter the woods below (careful of the chompers!) and use the the boxes to build a bridge along the purple path.
