Perhaps in a fanfiction where there's an alternate universe. In this universe, Billy and Mandy are normal kids without all the spooky stuff around them. They participate in a school play where they have to kiss as part of the script, and this kiss makes them see each other in a different light, starting a romantic sub - plot in this otherwise normal world for them.
You can also start by introducing a new character who challenges their relationship. Maybe a new girl has a crush on Billy and Mandy gets jealous. In the heat of an argument to claim Billy as her friend (or more), she kisses him. This would create an interesting starting point for the fanfiction.
A possible plot is that the kiss was part of a bet. Billy lost a bet to Grim and as a result had to kiss Mandy. But then, unexpectedly, Mandy didn't mind as much as she thought she would and it led to a series of comical and heart - warming events in their little group.
Once upon a time, Billy and Mandy found themselves in a rather strange situation. Billy, with his goofy charm, started to see Mandy in a new light. One day, while on an adventure in the Underworld, Billy accidentally saved Mandy from a spooky monster. Mandy, who was usually tough as nails, blushed a little. From that moment on, Billy couldn't stop thinking about Mandy, and Mandy began to tolerate Billy's presence more than usual. As time passed, they started to share little secrets and jokes, and a tender love began to bloom between them.
One common theme is friendship. Their unique dynamic can be explored in many ways, like how they support each other through tough times. Another theme could be adventure. Writers might send them on exciting quests or into mysterious places.
Granny from the series could be a great addition. She could act as a sort of wise advisor to Mandy and Billy, providing them with valuable advice based on her own experiences. Her no - nonsense attitude could also add some humor to the story, especially when she scolds Billy for his silly mistakes or when she encourages Mandy to be more open - hearted.
One common theme is the exploration of their unique relationship. Given their different personalities in the show, fanfictions often play with how they interact and grow closer. Another theme could be adventure, where they go on some crazy quests together.
One common theme could be the 'opposites attract' idea. Billy is often clumsy and simple - minded while Mandy is more cynical and intelligent. Their differences can create interesting romantic dynamics in the fanfiction.
Definitely not. 'Pulp Fiction' has a unique set of characters that are part of the Tarantino - created underworld. There's no place for Billy or Mandy in that movie. It's all about the likes of Marsellus Wallace, Butch Coolidge, and other characters involved in the violent and gritty story. So, you won't find any mention of Billy or Mandy in 'Pulp Fiction'.
