Grandpa Smurf

From Smurfology

Grandpa Smurf is one of the main characters of the Smurfs cartoon show, who has appeared on the show from Season 6 to the end. He is the father of Papa Smurf and has made a 500-year journey around the world to find the purest of the four primal elements in order to restore power to the Long Life Force Stone. His knowledge of the world is a valuable asset to the other Smurfs, not to mention various items he kept stored away in his beard such as a magical traveling hot-air balloon. He is identified by his yellow Smurf hat and pants, and by a very long white beard with a drooping moustache, in addition to white head hair that has grown around the back of his head. He usually carries around a walking stick, and though he's usually slightly hunched over holding his back, he's very spry for a Smurf who is twice Papa Smurf's age.

His character was voiced by Jonathan Winters.
