I think what the writers were trying to do for those disapproved ones, was trying to find new ways to defeat the sharpteeth. You've gotta at least give them credit for trying to be creative.
LBT 10 was some of the weakest performances I have ever seen from a sharpteeth (especially from Three sharpteeth!).
Well, they were at a disadvantage. It's not easy to balance on a slope and fight at the same time. They were up against 4 fully grown longnecks, all of which most likely knew how to fight sharpteeth, despite one being injured. Add in a bunch of other factors that mainly revolve around timing, and they can't help but look pathetic in their situation.
I wonder if Littlefoot would never feel compeled to think of his mother when he sees Chomper and his parents. I admit though that the topic is extremely difficult and there is no "solution" that wouldn't be at least somewhat utopic.
Hmm, I think Littlefoot thinks of his mother quite regularly. A horrifying image such as that does not leave peacefully. It sadly haunts you for the rest of your life. How he's able to stay happy through his life is beyond me. If you ask me, Littlefoot has alot of courage to face his demons within.

(This requires more wisdom than knowledge to understand.)
Well, it's late here, and I'm tired.
See ya in the morning. :^.^:
