Well, in some Happy Tree Friends human fanfiction, the authors might take the concept of the show's dark humor and translate it into a human context. Maybe they create situations where the characters accidentally get into trouble in a more believable, human - scale way. Another idea could be that the fanfictions explore the relationships between the characters in a more complex way than in the original show. For instance, delving deeper into the love - hate relationships among them.
Some Happy Tree Friends human fanfiction could revolve around the characters' families. Since they are human in these fanfictions, there could be stories about their family dynamics. How their parents influenced them, or how they interact with their siblings. Also, there might be fanfictions that deal with the characters' dreams and aspirations. What do they want to achieve in this human - like world? It could add a new layer of depth to the characters that we don't see as much in the original animated series.
One interesting story could be about how the characters overcome a big natural disaster in their forest. For example, when a huge flood comes, they have to work together to build rafts and find high ground. It shows a different side of the usually comically violent characters, highlighting their survival instincts and ability to cooperate in extreme situations.
Some fan stories revolve around alternate universes for Happy Tree Friends. In one such story, all the characters are superheroes with their own special powers. Lumpy could be a clumsy but well - intentioned superhero who always accidentally causes more trouble than he solves, while Flippy could be a war - hero - turned - superhero who has to battle his inner demons (literally, in his case) while trying to save the day.
A crossover with 'My Little Pony' could also be fascinating. Picture the pastel - colored ponies meeting the cute but accident - prone HTF characters. There could be a lot of confusion as the ponies' magic might not work in the same way in the HTF world. The HTF characters would be intrigued by the ponies' kindness and harmony - based society.
You can start by looking on fanfiction websites such as Archive of Our Own (AO3). It has a large collection of various fanfictions, and there's a good chance you'll find Happy Tree Friends human fanfiction there. Another option is FanFiction.net, which also hosts a wide range of fan - created stories.
One idea could be a time - travel plot where a character goes back in time to prevent a tragic event that usually happens in the regular Happy Tree Friends episodes. For example, Flaky could go back to stop Cuddles from getting into a dangerous situation that leads to his untimely death.
One interesting plotline could be when Flippy's military past accidentally surfaces during a seemingly normal day in the forest, causing chaos. Another could be the interactions between Flippy and Flaky, like when Flaky's timid nature clashes with Flippy's unpredictable outbursts.
One interesting story could be about a human character who becomes a train engineer in the Thomas and Friends world. They might have adventures trying to understand the unique personalities of each train, like dealing with Thomas' eagerness or Percy's sometimes timid nature.
One interesting Thomas and Friends human fanfiction could be about the engineers as humans and their adventures in maintaining the trains. For example, they might face a big challenge like a natural disaster threatening the railway and they have to work together with the 'humanized' trains to overcome it.
The contrast between their personalities. Flippy's unpredictable and sometimes violent side due to his PTSD, and Flaky's timid and cautious nature. It creates a lot of potential for drama and character development.
In some fanfiction, a human who is an artist finds a fairy tail. The fairy in the tail has the power to bring art to life. The human and the fairy work together to create a beautiful, magical art gallery. They invite other humans and fairies to see their creations, spreading happiness and harmony between the two worlds.
