that made Towelie (Tynacorp) in an effort to get their Okama Gamesphere. The plot gets increasingly thick, involving aliens trying to take over Earth using genetically modified towels. Throughout the story, the boys show no interest in these revelations, as they single-mindedly want nothing more than to retrieve their Okama Gamesphere; in spite of their utter indifference, the increasingly complicated plot continues to surround them and the two sides attempt to play them against the other. In the midst of a confrontation between the military and Tynacorp, the boys find their Okama Gamesphere, but before they can play for long the building is blown up in order to kill the aliens that want to rule the world. Kenny McCormick falls in a pool of lava, but the other boys and Towelie escape with the Okama Gamesphere. The boys and Towelie then go home and play the Okama Gamesphere. As they share a laugh, Cartman comments to Towelie, "You're the worst character ever, Towelie", to which the towel complacently replies, "I know." Production Towelie's catchphrase, "don't forget to bring a towel," originated on a boat trip the writers took, during which people were constantly telling each other "don't forget to bring a towel," with the phrase having eventually morphed into "Towelie says to bring a towel." Parker and Stone have explained that they were becoming increasingly aware as to how heavily merchandised and exploited their creations were becoming, and created Towelie to poke fun at this. They designed Towelie as a shallow, two-dimensional (both literally and figuratively) character who has no real purpose except to "spout catch phrases and merchandise the hell out of." This is the reason for the fake commercial during the show, and why Cartman calls Towelie the "worst character ever" at the end of the episode. Shortly after "Towelie" was originally broadcast, South Park Studios, the official South Park website, featured T-shirts and hooded sweatshirts based on the episode. The shirt design featured a waving Towelie saying, "Don't forget to bring a towel." The console in "Towelie" was originally a PlayStation 2, whose name was used during the production of the episode, in its storyboards and scripts. The fictional console ultimately used in the episode, the Okama Gamesphere, was seen as a reference to the Nintendo GameCube. Before the episode cuts to a commercial break, what appears to be a fake commercial is shown advertising Towelie merchandise;
