Walkthrough for Grunt #2 and Grunt #3 together ... Part 3

Part 2 ... Satisfying the fourth set of CPSez .
Description of what to do
Shovel #2 and SpongeGun #3:
SpongeGun #3 stepz on the Question Mark Switch (QMS)
This allowz him to shoot the enemy Grunt off the Yellow Toggle Switch (YTS) he is standing on, onto one of the Arrowz , so that he returnz and togglez the YTS .
This will trap the RO between an Arrow and a Two-Way Arrow facing in the opposite direction.
(Later on, a Grunt will be able to collect the six Coinz the RO has been passing over.)
Oh! Remember that Toy you have been lugging around for a while? Give it to your buddy ... the one who "needs this".
Now it is time to choose a BW , and go through it.
If you have chosen the correct BW , you will be able to reach this place (where the Green dot is).
Use your pink gun to shoot the enemy Grunt toward the other enemy Grunt .
(They are not on the same team, and the enemy Grunt will give a Toy to the other enemy Grunt .)
If the Toy breakz before the enemy Grunt fallz into a Hole , restore your last SAVEd game and try again.
Then move on to stand on the three GHSez , to squish the ROz against the GPz .
(Your buddy will thank you for that!)
When Shovel #2 finishez the job of filling in Holez , etc., you may go through your BW .
