Freeing Grunt #1
Grunt	Description of what to do
Bare-handed #1	Stepz out in faith onto an Arrow ... heading toward a Hole !
Sponge Gun #4	Sees his predicament and firez a sponge at the Arrow just before the Hole . Grunt #1 and the sponge arrive at the same time, and Grunt #1 keepz walking. Seeing that the walk could be endless, he headz back to the STS area. Timing it perfectly, he shootz a sponge at an Arrow and (once again) Grunt #1 and the sponge arrive at the same time and the result is a new tool (Tool #4) is acquired.
Springz #1	Stepz out in faith onto an Arrow and bouncez around the Hole ... perhapz endlessly.
Sponge Gun #4	Sees his predicament and stepz on the STS and goez through lowered SPz. Step 1: From there, he takez aim at an Arrow and letz fly. The result should be Springz #1 landz on another Arrow . But wait! Here he comez, back around again ... to go "loop-de-loop"! It seemz you need to send a sponge to an Arrow that will deflect the target to another Arrow which leadz to another Arrow ... and out. Or possibly to an Arrow that will deflect the target to another Arrow ... and out. Try as you might, you just cannot hit either Arrow ... from here. Gotta get closer. Repeat Step 1 successfully. Step 2: Activate the STS (at the proper time) and step onto the lowered SP to the north and take the shot. Step 3: repeat stepz 1 and 2 until Springz #1 is in control of his fate. One thing to remember; Grunt #1 was hit twice just in order to get the tool. Springz #1 has to be hit twice more to get him to freedom. Is 16/20ths of health sufficient? How many timez did you fail? Zap Cola?
