Santa's Little Helper event; however, their plan fails and a drunk shark that's discovered at the event becomes the new mascot instead. Santa's Little Helper gladly returns to the Simpson family. Santa's Little Helper's initial appearance on "The Simpsons" was in the first episode of the series, "Simpsons Roasting on an Open Fire", which aired on Dec. 17, 1989. Since then, he has become a recurring character. "The Simpsons" creator Matt Groening told "TV Guide" in 2000 that "we [the staff] painted ourselves into a corner with our Christmas episode. Once we wrote the dog into the show, we were stuck with him."
The Call of the Simpsons DVD review of the first season, David B. Grelck gave the episode a rating of 1.5/5, adding "the surrealism of Homer as bigfoot is a major misstep. This type of gag would be very different today, if done at all." Jon Bonné at MSNBC called the episode "a perfect example of the first season’s bizarre and fruitful balance between edgy humor and softly-drawn neuroses" and stated that "it was this combination that made Groening’s shorts for the Ullman show so compelling, and ultimately what made it possible for "The Simpsons" to break the molds of network television."
