The Land Before Time XV: Beast of Crystal Tooth Cave

The Fifteenth addition to the Land Before Time saga, where Littlefoot and the gang discover the magical wonders of a Cave called "Crystal Tooth Cave".

Plot
Littlefoot mourns for his mothers death since it was the day his mother died, Petrie tries to cheer him up by doing tricks with five walnuts (hard seeds), but trips and all bonk his head, but to no satisfaction for Littlefoot. Ducky tries to give a joke "What do you call a Spike Tail with no Spikes?" "A Plain Tail", but not one smile from Littlefoot. Cera actually comes to cheer him up by telling him it's the day they met, also showing she regrets what she said about her back in the canyon, as Cera was about to give him tree star, Spike interrupts with a "wind tail" (flatulence) which spread-ed across the Great Valley, which suffocated everyone (Mr. Threehorn, Grandpa Longneck, Petrie's family, Ducky's family, and five Muttaburasaurus's), including Littlefoot, Littlefoot then smiles for their trying to give him compassion for the loss of his mother, then goes off into the forest, Cera then glares at Spike for almost killing them with a wind tail.

Ducky feels sad for Littlefoot, then her mother came to tell Ducky that her friendship is dear to Littlefoot, but wouldn't replace what he lost having a mother, Petrie's mother did the same thing to Petrie and Petrie starts to understand what Littlefoot is going through. Spike did a wind tail again but this time in the watering hole, and killed the fish, Mr. Threehorn backs away from the watering hole to tell Cera he too felt guilty for not thanking Littlefoots mother before she died, and felt terrible as Cera did. Chomper noticed Littlefoots sorrow, and knew what it's like to lose a mother, along with Ruby. Grandma and Grandpa Longneck also mourns their daughter's death. Grandpa Longneck then confesses that what Bron told Littlefoot about leaving to find a new home for them was a lie, Grandma knew all along, but Littlefoot was devastated realizing Bron lied about a dinosaur telling him his mothers death was not Rooter as he remembered not mentioning his name when Bron mentioned it. Thus Littlefoot ran off into the mountain face after realizing his relationship with Bron was based on a lie made by his Grandfather just so Littlefoot wouldn't betrayed by Bron leaving the herd to rot.

Grandpa was horrified realizing Littlefoot overheard them, Cera was more worried and asks the others to find him, as they were off Pterano returns to inform them that Littlefoot had entered Solar Mountain, Mr. Threehorn then mentioned a legend of a Cave known as Crystal Tooth Cave, and any one who entered there must face "The Beast", a mysterious creature that catches anyone who intrudes it's crystal covered walls and crystal covered floors and turn them into Crystal husks. Petrie then asks does it eat Fliers, but was given a shook head, but Cera gets impatient and takes the gang to where the entrance to Crystal Tooth is.

Littlefoot still hurt from learning the truth, sees a cave entrance that looks like Sharptooth only with Crystal teeth, Littlefoot as he ventures into Crystal Tooth, he then sees himself in a mirror notices that the crystals shine like the sun or moon, and he was marveled on how wonderful it is, he then saw the same Sharptooth that killed his mother, and the same Sharptooth that attacked his friends on the Mysterious Island as if they were ghosts, as Littlefoot thought sharpteeth killed him, he realized they were illusions based on his fear. Cera then followed the same footprints Littlefoot left, she then looks at the entrance but was at first hesitant but Spike, Ducky, Petrie, Chomper, and Ruby manage to keep up and gives Cera confidence. Meanwhile Littlefoot actually was more far away from where Cera and the gang are, then reaches the spring where green food grows and gets hungry, as he eats the tree stars that grew on the wall something is coming up behind him, and Littlefoot wasn't sure what it is until he looks behind him and sees the "Beast".

Cera then as she laments she hears Littlefoot scream, and tries to rush to his rescue but trips on a crystal on the floor, then falling down a pit. Chomper notices Cera's predicament and brings the gang to rescue her, Ducky as she got there notices that Cera is blocking a vent, so she has Spike block the other vent and lets his fart her out the other end, Cera then lands the spring and wasn't hurt, but glares at Ducky for her awkward idea. Ruby then notices Littlefoot's footprints stop right at where he was eating, then Petrie assumes he got "Gobbled up, by the Beast". Although Petrie's theory convinced the others Cera wasn't buying it, and notices that there is a giant dead spider (Mesophele), and probably caught Littlefoot in the web.

Littlefoot wakes up in an unknown part of the cave sees golden crystals above him, and he was covered in a fur blanket, and laying on a pillow (made of fur and a magical sponge material) then he notices that he was in a nest made up of layers of animal hide, wood, and crystals as hard as Iron. Littlefoot gets up and notices a bite on his shoulder (From the Giant Spider), and realizes the beast is actually a female dragon that is actually lonely and believes Littlefoot is her son, Littlefoot then notices that the eggs look just like his from years a go from the time before he came into the great valley. Littlefoot then notices three mirrors that he never saw before in the cave, and when he looked into the mirror he realized that Bron lied about going to find new land for his family, but abandon them because they were old an weak, and in the second mirror he notices that the Dragon named "Arya" did not start at the great valley either but had an egg with Ashar her mate, but then Littlefoot noticed that an egg fell into the their cave and was smashed on the floor, then a Longneck's snout stole their egg, and manipulate Littlefoot's "mother" into believing that her egg was saved, Littlefoot was devastated. Rooter's voice tells the audience "now you know, the connection, and why Littlefoot is not like a normal Longneck".

Cera meanwhile with the others, started to climb the walls of the cavern and then noticed Spike was getting winded, Petrie tries to entice him with a Tree Star, but awakens a swarm of Giant Spiders, Spike and Cera fight the spiders, while Ruby and Chomper get Ducky and Petrie away from the Spiders. Cera then realized that the Beast was no evil creature but in reality an excuse to cover the spiders, as Cera was cornered on a ledge then a Titanboa grabs the spider and eats it, unfortunately the snake now hungers for a Threehorn, and goes after Cera, but salvation came when a mysterious shadow and a roar came and scares the serpent off. Spike, Chomper, Ruby, Ducky, and Petrie rushes to find Cera and notices she disappeared like Littlefoot.

Grandma back in the Valley then confesses that she stole an egg from Arya and Ashtar long ago, Grandpa was confused and in disbelief until he heard about the facts from Pterano about draconians can take form of the one who lays it, as a survival technique. Mr. Threehorn then concludes that the Beast is actually a Fire-Tooth (Dragon), he thought they were wiped out from the earth shake proving them wrong. Grandpa now realizes that why Grandma really wanted to keep Littlefoot from the Mysterious Beyond.

Cera wakes up the same way Littlefoot did and was also shocked when she encountered Arya, but Littlefoot explained everything, Cera was amazed to realize that he wasn't just a Longneck, but a Flame-Tooth as well, outside the mountain Littlefoot's mother's spirit was hurt to realize the lie that Grandma told her, but for not telling Littlefoot about Bron. In three days Cera and Littlefoot became care takers of the Flame-Tooth, eggs and accepting Arya and Ashar as his parents, but in the mountain showing a starved Spike, along with a tired out Ducky, Petrie, Chomper, and Ruby they then see green food at the top of the Ridge they have been climbing on the past three days, and helped them selves while Chomper chases a "Boing Boing" (Leptictidium) Ruby tries to stop Chomper, but both run into a "Hoofed Sharptooth" (Entelodon), while Spike, Petrie, and Ducky encounter a "Sabre-Fang" (Smilodon), both were chased by the beasts, but Littlefoot and Cera rescue them, Littlefoot reveals that he tamed a Sabre-Fang named "Fangs" and actually reveals that he is no threat to them. Cera is seen taming the Hoofed Sharptooth, and causing it to leave,

Petrie was amazed at their home for three days and got to meet Arya and Ashar, Spike was at first frightened but grew to like them. Littlefoot tells the gang that this is his home now, and his real family, which shocked the gang including Cera. The Folks from the Great Valley enter the cave, and hear Littlefoot's words, Grandma and Grandpa didn't blame Littlefoot for saying it, but they wanted to make it up to him, but they didn't realize that another Flame-Tooth was following the folks and followed them quietly. Arya then tells Littlefoot that he knew them longer than her and Ashar, and believes he is still hurt on the confession he overheard, as the echos of Grandma apologizing for lying to him, and his mother, and Grandpa telling Littlefoot no matter what may come, he is still his grandson. Littlefoot was touched by this and so was Ashar and Arya so they decide to go down to meet the folks.

As they did the Flame-Tooth came and attack Ashar and Arya, but Grandpa and Grandma confronts the Flame-Tooth, along with Mr. Threehorn came to confront the Flame-Tooth. But the Flame-Tooth then faces off with Grandpa Longneck revealing him to be a deciver (shapeshifter) disguised a Bron, and even as Pterano just to get the young ones into the cave to bring Ashar out in the open. Littlefoot notices another Rogue Flame-Tooth came to attack Grandpa from behind to kill him but Cera manages to ram his leg to distract him. Ashar reveals their names Dracion (Red Flame Tooth), and Slark (Green Flame Tooth). Spike then sees the Serpent and causes it to attack Slark, but it went for Grandma instead. Grandma manages to beat the serpent with Fangs's help, and even the hoofed sharptooth that Cera tamed bites Slark in the Leg then causing him to crash into a wall, and Crystals avalanches on him. Ashar then lounges on Dracion, but fails to beat him as Dracion was about to crack his neck, and pined Arya down, Littlefoot shows a fear of losing not only a mother again, but a real father too, he then notices his back was cracking and molts into a Flame-Tooth to confront Dracion, then uses the Illusion of Sharptooth to distract Dracion, Littlefoot then noticed Ali who all this time was with the folks trying to find him since she entered the Great Valley with the herd, both Littlefoot and Ali both flee from the ever persistant Dracion, as Dracion cornered Littlefoot and Ali, he sees the Spirits of Bron and Littlefoot's mother, and Sharptooth (The Real one) came to face Dracion only for them to fall into a deep cave with a fate unknown.

Littlefoot believes Ashar is dead, but notices an eye opens, and both share a bonding moment, along with Arya. Cera was glad to see Ashar and Arya are all right, then Ashar and Arya were thanked by the spirits for helping not only Littlefoot, but for being honest, and more true to their adoptive son, and for forgiving them. Littlefoot bonds with them and bids them goodbye as the rest in peace. Petrie faints when the problems over.

Arya and Ashar have been accepted into the Great Valley, and it's inhabitants, including Sharpteeth since they actually are now the cleaners of the valley whenever a dinosaur dies but mostly are seen hunting mutant longnecks (Indrikotheres). It ends with the narrator saying "it doesn't matter where you came from, or who your blood relates to, it's the people who love you that makes a true family, and this is not entirely the end but a brand new beginning."
