Secretz:

 

Red Warp #1: The trigger is in the r/g pyramidz. Following the path to the left, you come to a tile with pebblez on it. The warp opens at the beginning of this section and Gauntletz should enter.

 

Re Warp #2:   The trigger is on the north pointing arrow on the right side of the rather speedy rolling ball and should be activated by the Shovelz. After eliminating the gunhat, step on the arrow, go through the warp, and come back.

 

Red Warp #3: The trigger is on a tile covered with pebblez near one of the BOT switchez. Anyone can use it.

 

Red Warp #4: The trigger is on the path of the black pyramidz. Anyone can use it.

 

Secret Switch:            The switch is in the hole that Talc shot the first gunhat into. Obviously, Capt. Crater and his shovel must be the one to activate it. Using as many diagonals as possible, he will pick up the warpstone and head south to the warp.
