The Sandman is a character that appeared in the cartoon show episode "The Dark Ness Monster". He lives in the Land Of Nod where he sleeps until dusk, at which point he goes around putting people to sleep with his special sleeping sands. In the episode, Papa Smurf and the Smurflings visit the Land Of Nod so they could awaken the Sandman in order to get the special sand to make Brainy a new pair of glasses. However, upon his awakening, the Smurfs found the Sandman to be a cranky old man who cared more for sleep than for helping anybody else out, replaced the kind happy sandman and so tried to put his visitors to sleep. Papa Smurf's persistent harmonica playing prevented the Sandman from going back to sleep, and so he offered to give the village leader his sleeping sands in exchange for something equally precious: a bucket of chocolate from the pool of the Dark Ness Monster. Papa Smurf agreed to do this and so he and the Smurflings went to the Dark Ness Cavern to get the chocolate from the Dark Ness Monster, who was now wearing Brainy's glasses, to make the exchange, which the Sandman faithfully kept his end of the deal by giving his bag of sleeping sands.
The Sandman makes another appearance in the episode "Lazy's Nightmare".
