After an incident which nearly cost Littlefoot’s grandmother her life, Littlefoot learns a series of lessons which his species call “Wisdoms”. Meanwhile, a trio of dim-witted Beipiaosauruses named Loofah, Doofah and Foobie arrive in the Great Valley and behave in a strange manner towards Littlefoot and the gang. Littlefoot is determined that they learn the “Wisdoms” and the journey to the one place the trio have dreamed of, Berry Valley, begins.

Littlefoot and his pals set off in search of a “stone of cold fire” that fell from the night sky. Since he’s the only one who has seen it though, nobody really believes him. Littlefoot’s uncle Pterano offers support only because he thinks the stone has secret powers and wants it for himself but conceals this from the rest. The young dinos must figure out the truth, before Pterano gets the power.
