What a coincidence niteowl-I've just been playing MO and I got Munch into the same place by jumping on the mines to get over the wall.
Your right, it's a shame the gluks don't say anything. But I guess OWI never expected us to do this! I'm surprised that the gluks even do anything when you hit them!
There is also a part in Resivour Row where you can do this same thing-but it's too hard to explain and it's not worth it.
Also my first time playing MO, I accidently skipped a gluk (in resivour row) and finished the level! But I can't remember how...
