I finished this adventure. It was amazing.
The chomper part did stump me for some time, but your hint helped a lot.
The crab part, however...
I actually didn't have trouble with it, once I found out that I didn't need that confounded
flo trick that I couldn't pull off.
I thank you for this adventure, Wonderman!
Oh, one other thing...
I think "than" and "ncessary", was it? Towards the end, in the
final cavey place encounter and clearing, respectfully. They're not spelled right. Just wanted to let you know.

Now to link this...
