<P> Over the next few days, incidents of bad luck plague the Valley . After a tornado hits the Valley, the adults blame Doc, as the misfortunes apparently occurred after his arrival, while Littlefoot blames himself and his friends, recalling the breaking of Saurus Rock . Eager to exonerate Doc, Littlefoot attempts to take one of the Sharptooth's teeth to replace the broken stone . In the process, he discovers the Sharptooth is still alive . After temporarily escaping it, Littlefoot is attacked by a Tyrannosaurus, with Grandpa intervening, having been led there by Littlefoot's friends . Soon the Allosaurus returns and works together with the Tyrannosaurus to take down Grandpa Longneck . However, Doc comes to the rescue . The sharpteeth charge through and run into the rock spire and fall down . Doc and Grandpa work together (now that the sharpteeth are down) to pull down a category of rocks and crush the carnivores to death . When the carnivores are now defeated (after the two longnecks have encased them into a pile of rocks), one of the teeth from the Allosaurus falls out and lands on the ground . Then the children use the broken out tooth (from the Allosaurus) to repair Saurus Rock . </P> <P> Doc departs, remarking that Littlefoot already has a hero on whom to depend on, referring to Grandpa . Littlefoot asks Grandpa if the bad luck will finally be over . They both agree that while there is no such thing as bad luck, there is also no harm in making sure . Littlefoot and Cera later build a legend of their own based on this new paradigm, portraying Grandpa Longneck as a hero and savior called "The Great Dinosaur". </P> <Ul> <Li> Kenneth Mars as Grandpa Longneck and the narrator . </Li> <Li> Thomas Dekker as Littlefoot </Li> <Li> Anndi McAfee as Cera </Li> <Li> Aria Curzon as Ducky </Li> <Li> Jeff Bennett as Petrie / Spike </Li> <Li> Kris Kristofferson as Doc </Li> <Li> Miriam Flynn as Grandma Longneck </Li> <Li> John Ingle as Cera's father </Li> <Li> Nancy Cartwright as Dana </Li> <Li> Sandy Fox as Dinah </Li> <Li> Danny Mann as Allosaurus </Li> </Ul> <Li> Kenneth Mars as Grandpa Longneck and the narrator . </Li>
