Would you have ever thought that there would be a market for Rugrats-themed porn? Because there is. Recently, porn production company WoodRocket(NSFW) launched Tugrats, a porn parody based on the popular Nickelodeon cartoon that many of us eagerly watched on Saturday mornings. Before rushing to judgement, the characters are proper, sexually-curious adults, though they suspiciously wear the same clothes (Tommy is still in his diaper). You, like many who’ve heard of the parody, might be asking: how in the world has a legitimate adult film based on a childhood cartoon centered around talking babies been made? Because there’s demand.

Porn parodies are massive right now. Pornhub’s Year In Review report revealed “Rick and Morty Porn Parody” was the second most searched term of the entire year, bested only by “Porn for Women.”

“I think we made a porn parody of one of the best shows on TV (if not the best),” Lee Roy Meyers, the man behind WoodRocket’s celebrated porn parodies–including the aforementioned Rick and Morty spoof–tells Playboy. “Rick and Morty is a hilarious show with lots of sex jokes. It was made for porn fans.”

The category’s reign over other genres should come as no surprise. Fantasy is the driving force behind pornography, after all, so it makes sense that as porn becomes more and more casually regarded audiences will yearn to feel more connected to the material, which porn parodies instinctively do as we’re already familiar with its characters.

The industry loves porn parodies too. Why? Because they’re cheap to make and attract big audiences. This is rather ideal, as the industry is looking for ways to recoup dwindling profits at the hands of streaming porn websites hosting stolen content. The material has latches onto the past–a time when traditional porn was a more lucrative business– and exploits it sexually and financially for cheap.

Since audiences often know of the source material’s characters, marketing a porn parody is a cinch. “When people love a show or movie or game, they want to watch as much of it as possible. In porn, you really get to see everything,” Meyers says. “I think that’s the best built-in marketing campaign there is.”

Sunny Rodgers, clinical sexologist and ambassador for the American Sexual Health Association, agrees, insisting one of the reasons parodies are so popular is they have an existing fan base. “These parodies aren’t about a particular starlet. Well-known, beloved characters are the stars here. And for true fans, they view anything related to their genre of choice or their favorite popular mainstream franchise,” she says. “I’m sure porn producers realize this when they choose which media franchise to turn into a sexually-fueled spoof. Anything with an existing large audience base is almost guaranteed to be successful.”

Rodgers argues we’ve all had a secret crush on a fictional character in the past, and porn parodies let us explore what seemed like an impossible fantasy. “The characters in mainstream movies are just that, characters,“ she says. "So, it is feasible for people to believe that they have a hidden naughty side that can be acted out in porn.”

She uses Daphne from Scooby Doo as a popular example. “Her love of dogs and mysteries made her the perfect fantasy for a lot of people, who were beyond thrilled when Scooby Doo: A XXX Parody was released.”

According to Meyers, the formula for a successful porn parody must include three things: vaginas, boners and money. “It’s important to first find porn performers that can do impressions of the characters they’re parodying and great makeup artists and wardrobe folks who turn the performers into the characters as closely as a porno budget allows,” he says. A set that reflects the series is important as well, as are jokes that wink to the source material.

If you’re new to porn parodies, Meyers believes there is "nothing weirder and thus more fun” than Edward Penishands (you have to watch this scene of Eddie trying to eat spaghetti) and Beaver and Buttface, attesting they’re both classics in the genre.

As far as his personal works, Myers recommends Strokemon, Ten-Inch Mutant Ninja Turtles, SpongeKnob SquareNuts, Game of Bones and Hamiltoe. Then again, your best option is a parody based on a series you love because deep down, we’re all perverts and we want to watch our beloved fictional characters have gratuitous, over-the-top sex.
