The Land Before Time VIII: The Big Freeze

Littlefoot (Thomas Dekker) is a young longneck who has always had Spike beside him, so the day Spike leaves to live with other spiketails hits hard. An ice storm has trapped every dinosaur family in the Great Valley, and the spiketails, who eat more than anyone, volunteer to go. Charles Grosvenor sends Littlefoot, Cera (Anndi McAfee) and their friends out with Mr. Thicknose to bring Spike back before the valley's food runs out.
