Barney: We Love Our Family

Littlefoot befriends with a mysterious, fun-loving dolphin-like creature named Mo, who is trapped in "new water" caused by heavy rain. The gang then goes on an adventure to the "big water" to bring Mo home.

When the water supply to the Great Valley is blocked, Littlefoot and his friends must cooperate with a group of bullies to find the reason the cause.

Littlefoot learns a series of important lessons following an incident that nearly costs his grandmother her life. Soon afterwards, three dinosaurs arrive claiming they have lost their way.

As the Great Day of the Flyers nears, the Great Valley's flying youngsters are eager to participate in the annual exhibition to show off their skills. Everyone, that is, except free-spirited pterodactyl Petrie, whose individualism causes problems when it comes to staying in formation. Enter his dinosaur pals Littlefoot, Cera, Spike and Ducky, who encourage Petrie to embrace his uniqueness.

The Great Valley turns barren and herds of dinosaurs have to find another place to inhabit. Cera, Littlefoot and Petrie, all kids, leave to find food and get stranded on a lush unknown island.
