Beerhead, this is what MaG says about the batteries in her WT:
Take the scrub brush.
Batteries (revised): The placement of the batteries is random and not shown by the crosshair-hotspot icon. There are 5 possible places that the batteries can be located: left and right edge of the rock ledge at bottom right; top of the mountain at left; top left edge of the mountain at right and dark wide path of the far mountain at center of screen. Take the batteries.
Hope you can go on.
