The Land Before Time VI: The Secret of Saurus Rock

Littlefoot's grandfather tells the children legends about how their universe was created and about the Lone Dinosaur who protected the Great Valley. The tale describes the Sharptooth's defeat, the Lone Dinosaur's scar, and the birth of Saurus Rock. It also warns that damaging the monolith could bring bad luck to the valley.

In ancient legend, the Lone Dinosaur battles the Sharptooth to defend the Great Valley and bears a scar across his right eye. After the fight, a huge monolith emerges from the earthquake and becomes known as Saurus Rock. The myth warns that harming the rock invites bad luck on the valley.

The next day, Littlefoot slips off a cliff and is rescued by Doc, a scarred Diplodocus who knows the valley well. Littlefoot notices Doc's eye scar and his knowledge, which makes him wonder if Doc could be the legendary Lone Dinosaur. The rescue leaves him curious and impressed.

Inspired by Doc, Littlefoot narrates the legend to his friends, weaving clues that support his hunch about Doc being the Lone Dinosaur. The tale stirs curiosity and foreshadows the coming journey to Saurus Rock. His storytelling also deepens the group's bond with Doc.

Dinah and Dana, Cera's infant niece and nephew, sneak off toward Saurus Rock, drawn by the rock's mystery and the legends surrounding it. They slip away unnoticed while the others are distracted. Their curiosity sets the stage for the subsequent events.

When Dinah and Dana go missing, the friends deduce that they have headed for Saurus Rock. The group bands together to search for them and to confirm the legend's danger or promise. The dynamic shifts as the kids realize the real stakes of the quest.

Littlefoot and friends reach Saurus Rock and spot Dinah and Dana at the top. They climb to rescue them, but the twins slip and fall, breaking off one of the rock's teeth. The moment intensifies the peril and the need to protect the rock.

An Allosaurus pursues the group, threatening their escape. They cross a gorge on a suspended log, but the log breaks under the carnivore's weight and it plummets to its apparent death. The narrow escape reinforces the danger in the valley.

Cera's father scolds her for not protecting the twins, reminding her that she must be watched and stay responsible. The moment adds pressure on her to prove herself and to support her friends. It also hints at the growing tension between duty and independence.

That night, Littlefoot dreams of Saurus Rock fracturing and the monolith collapsing. Grandpa Longneck comforts him and reiterates the warning about bad luck, steering the conversation toward courage and responsibility. The dream plants seeds of doubt and resolve.

In the days that follow, misfortunes plague the Great Valley: the watering hole dries up and a tornado tears through. Doc helps protect Littlefoot during the storm, while Dinah and Dana recount Cera's bravery to her father. The valley's pain tests everyone’s resolve.

Despite Doc's help, the adults blame his sudden appearance for the valley's troubles. Littlefoot blames himself and his friends for the perceived failure to protect Saurus Rock. The group spirals into guilt as they try to sort out responsibility and truth.

Determined to prove Doc's innocence, Littlefoot plans to take one of the Sharptooth's teeth to replace the missing rock tooth. In the process, he discovers that the Allosaurus is still alive and stalking the valley. The plan shifts from proof to survival as new threats emerge.

Allosaurus and Tyrannosaurus threaten the valley, and Doc arrives to help as Grandpa is drawn into the danger. The carnivores crash into a rock spire and are crushed, while the two long necks pull down the spire to seal their fate. A tooth from the Allosaurus falls out and is used to repair Saurus Rock.

Doc departs, telling Littlefoot that he already has a hero to depend on—Grandpa. They acknowledge that there is no such thing as bad luck, only the choice to protect one another. Littlefoot and Cera then craft a new legend depicting Grandpa as ‘The Brave, Great Dinosaur’ to honor his heroism.
