Border area

This is the area where the Rolling Rock (RR) will travel once (or if ???) it is released.
The puzzle will require two Gruntz (although you may be able to do it with only one) on the border.
One of the Blue Wormhole teleporterz (BW) will take a Grunt to the border.
This Grunt is intended to walk north to the Arrow in the far northwest corner of the map, then east to pick up a Megaphone and four Coinz .
If the solution has proceeded as the author intended it, he will step on a Black One-Time Switch (BOTS) and be prevented from continuing by a Black Pyramid (BP) … until released (by the RR, or a fellow Grunt) by another BOTS .
This Grunt wil probably be used later to complete what is necessary around the border.
The author intended another use for this Grunt, with another Grunt finishing the border work.
