The Land Before Time XIII: The Wisdom of Friends, directed by Jamie Mitchell, is the thirteenth movie in The Land Before Time series.
The film begins with the narrator relating how, due to the dangers of the dinosar world, all the different species of dinosaurs have had to learn ways to keep safe.
The scene then changes to Littlefoot eating treestars with his grandmother, when he tries to reach some treestars on a fallen tree across a deep canyon. Suddenly, an earthshake occurs and Littlefoot's grandmother almost falls to her death trying to rescue him. That night, Littlefoot awakes from a nightmare about his grandmother falling to her death in the canyon. Grandma comforts him and decides to tell him the Wisdoms, a series of rules about how to live and behave safely. While Littlefoot tells his friends about them they initially mock him for taking them so seriously, telling him how their parents also have their own Wisdoms that they teach them ("Say So") They then meet a trio of Yellow Bellies called Loofah, Doofah and Foobie, who are on the search for berry bushes. Their strange behaviour and odd appearance initially scares the young dinosaurs, but they lead them to a patch of berry bushes. As they proceed to eat every berry on the bushes, the Yellow Bellies tell Littlefoot how they are about to head to a valley full of berries, but they can't remember the name. Doofah mentions that the "Wise One" will know, but Loofah then remembers that it is simply named Berry Valley. After a drink and more discussion on Berry Valley, the Yellow Bellies head off to find the rest of their herd, so they can all make the journey to Berry Valley together.
The next night Littlefoot has another bad sleep story, involving the Yellow Bellies falling to their deaths in the same canyon as in the previous dream. This convinces LIttlefoot that he needs to help the Yellow Bellies and gets his friends to join him. When they eventually catch up with them, Littlefoot tries to each the Yellow Bellies some Wisdoms, but they don't get them, so Littlefoot decides instead, to accompany them to where they are meeting their herd, at a pile of rocks that look like a Yellow Belly. Foobie spots it in the distance, and the group set off.
On the way to the rock, Loofah gets thirsty and The Gang go on to find water while the Yellow Bellies rest. While resting the Yellow Bellies are attacked by a quartet of megalosauroid siblings who had previously heard Loofah shouting. After being chased the Yellow Bellies come to a dead end but The Gang pelt the Sharpteeth with stones from above and the Yellow Bellies bounce on their bellies to make rocks fall and the sharpteeth are soon buried.
Shortly after that the group find a watering hole, and Loofah and Doofah confuse Littlefoot and his friends by talking to the bushes around the water. However, it is revealed that these bushes are actually the Yellow Belly herd, who disguise themselves as bushed by burying their heads in the ground and sticking their feather tails in the air. The herd and the gang relax by the watering hole, playing and partying through the night ("Yellow Belly Bounce"). However, Littlefoot still sees no sign of the so-called Wise One, so decides to stay with the Yellow Belly herd until they reach Berry Valley. Meanwhile, the megalosaurs have dug their way out of the rocks and are back on the hunt.
The Yellow Belly herd keep moving across the Mysterious Beyond with Littlefoot leading them. After Cera asks if he knows where he is going, Littlefoot reasons that, since he has never been to Berry Valley, there is a chance they may find it if they go in directions he has never gone before. This logic doesn't make sense to Cera, but Loofah understands and Littlefoot is unsure if that is good or bad. Along the way they find water and berries but Littlefoot is worried because he came to teach the Yellow Bellies the Wisdoms but instead is beginning to think like a Yellow Belly. This leads Littlefoot to wonder how he can know what to think and whether he should follow logic, or his gut feeling. His friends reply that he should trust in his feelings to let him know what to listen to ("How Do We Know").
After the Yellow Bellies wake up from a snooze after eating all the berries in the berry patch, an intense storm begins. Littlefoot leads the Yellow Bellies up onto a plateau to shelter (one of the Yellow Bellies farted when he/she went under the plateau), but Doofah breaks away from the herd, heading off in her own direction. After the deluge ends, they search for Doofah and find her, wandering amiably about on a ledge. But a landslide of water and rock separates her from them, and the ledge threatens to crumble at any minute. Littlefoot convinces her to jump to them, and she make it just before the ledge collapses.
However, almost immediately afterwards the megalosaur pack returns. For some reason they go after The Gang instead of the Yellow Belly herd, but soon give up. They manage to trap The Gang and the herd and they seem doomed but then Foobie gives Littlefoot the idea to get the herd to sing and dance. The sheer volume of the singing stuns the sharpteeth, and all of the herd bouncing up and down causes the ledge to collapse, sending the Sharpteeth falling into the chasm below.
Foobie leads the herd to the Berry Valley and Doofah reveals that he actually the Wise One all along. After saying goodbye to the Yellow Belly herd, the Gang resolves to head home, despite having little idea where to go. But they head off anyway, reasoning that they'll find it eventually. Luckily they encounter their parents part-way into the journey, who accompany them home. Littlefoot and his friends reason with their parents that even though they went off on their own, the still followed all the Wisdoms, about staying in a group, keeping one's eyes and ears open, etc. But Grandma Longneck comments that they forgot the most important Wisdom of all: Stay inside the Great Valley.
Ducky admits jokingly that she and her friends have a bit of a problem remembering that one, and the group return home.
