I would like to see flying sharpteeth more frequently encountering the gang, especially Petrie, because in Dink, the little dinosaur, they were featured much more, and were more dangerous, even were in flocks.
I now remember, that in LBT IV, Ichy is not without Dil much of a threat, LBT V Ducky was kidnapped shortly by some flying sharptooth wanting to feed her offspring with Ducky. In LBT VII, there were Rinkus and Sierra with Pterano, but that is it, encountering angry flock of flying pterosaurs would be something, that I would like to see regularly.
