A Sweef is a Smurf-like alien being vaguely resembling a Swoof, except for having orange skin, pointy ears, and rather spiky hair. A Sweef also travels through space using rock-like saucer ships. In "Dreamy's Pen Pals", a Sweef visited Dreamy in the Smurf Village to return one of the letters he had addressed to the Swoofs, saying that he had "misspelled" his name. Sweef also looks similar to the comic book version of The Swoofs, due to having the same colored skin.
