The Adventures of Teddy Ruxpin(1987)

Teddy Ruxpin and his best friend Grubby travel to the Land of Grundo in search of a long-lost treasure. With the aid of brilliant inventor Newton Gimmick, they rescue a kidnapped princess and find themselves in the possession of six magical crystals, each with its own special powers. With the help of many new friends, the trio travel across the land, discovering the power of each crystal and uncovering incredible mysteries, all while thwarting the dastardly villain Tweeg. Unbeknownst to the heroes, the evil Supreme Oppressor, Quellor, and his Monsters and Villains Organization, are determined to take the crystals and use them to plunge Grundo and its inhabitants into perpetual darkness.
