The eleventh episode of Season 11 of South Park (Episode #164) is the second part of the Imaginationland Trilogy (also known as "Kyle Sucks Cartman's Balls"), and is about the evil imaginary characters breaking through the barrier dividing them from the good ones. Among the good characters running in fear there's a short elf-like boy in green clothes likely based on Link.

The third part of the Imaginationland trilogy features the final war between good and evil characters, and among these there's one clearly based on Ganondorf, the main villain from the Zelda series. His look is based specifically on his Ocarina of Time incarnation.

Kenny appears in this game dressed as a lady, complete with wig, looking almost identical to Zelda, specifically to her Twilight Princess incarnation. Kenny's wig is blonde, while Zelda had brown hair in that game, likely to reflect Kenny's natural hair color.
Curiously, in one of the first promotional images for the game, used as the cover of a special Game Informer issue, Kenny was shown without his hood, so the hair would possibly be actually his. Most notably the purple parts of the dress would be orange like his parka, likely to make him more recognizable.
The creators of South Park held no right over Nintendo's Zelda, but they only included a minor refence to the characters.
