Snorty (otherwise known as the Fake Smurf) was the name of a fake Smurf that infiltrated the Smurf Village in the comic book story "The Fake Smurf", the 1961 TV episode of the same name, and the 1981 TV episode of the same name. In the original comic book story, he was really Gargamel, who planned to destroy the Smurfs from within their village by becoming one. He had no name for himself the entire time that he masqueraded as a Smurf and was only referred to as "the fake Smurf" near the story's end. His physical impersonation of one, however, wasn't perfect -- he lacked a blue tail. By painting a piece of wood blue and then putting glue on it to stick it to his rear end, his masquerade was complete. In one of his attempts to destroy the Smurfs by collapsing the Smurf River bridge by cutting the ropes that supported it, he ended up being sent into the river when the bridge collapsed during him crossing the bridge. As he got out of the water, though, his fake Smurf tail fell off, finally revealing himself to be the fake Smurf.
Although Gargamel used Papa Smurf's laboratory to create a formula to help him return to his real human form, it ended up making him Smurf-size and thus easy for the Smurfs to cast him out of the village.
In the 1981 TV series adaptation of "The Fake Smurf", it was Hogatha who transformed herself into a fake Smurf with no tail. She was named Snorty due to her habit of regularly snorting in front of the other Smurfs. She used a pea to create a fake Smurf tail and sabotaged the bridge by placing Jokey's surprises under it instead of cutting the ropes that supported it.
