Spikez , and Sword Gruntz

There doesn't appear to be much here; Stopwatch (one minute, big deal!), Megaphone
… and a Yellow Toggle Switch (YTS).
A lot of opposition, for such a small reward. Not a high priority area to enter.
Spikez ? Hmmm!?! A SpongeGun might be useful to gently persuade those Gruntz to stand on some Spikez for a while … like the rest of their lives?
Then the path will be clear to enter later … if at all!
