The Land Before Time S01E23 - March of the Sand Creepers

Tiny, crab-like Sand Creepers have invaded the Great Valley - and they're driving everyone crazy! Ducky has her work cut out for her as she tries to protect the Creepers from all of the larger dinosaurs in the Valley. Meanwhile, Littlefoot and the other kids find themselves completing increasingly difficult tasks while trying to convince a cranky old Sand Creeper to lead the other crabs out of the Great Valley.
