Ben was deep in thought about the best way to damage the crabawls.  It suddenly looked like he was struggling with something.  "No, well..." he said to himself.  He thought for a moment more before turning to Karen.  "I thought of something but it's pretty much suicidal.  The trent said that they don't chew, they just swallow and that you could live in there for a while.  If you got swallowed by it and then used your fire inside of it, the damage to it would be immense.  I just can't figure out how to get you out of it after.  I know it's a stupid idea and I don't even know why I said it just now."
