Yes. In some interpretations, it can be seen as having elements that could be related to a flounder fanfiction. There are unique and fantastical elements in Harry Potter that might give that impression, like the magical creatures and the strange new world which could be paralleled to the imaginative concepts often found in fanfiction.
I'm not entirely sure specifically about 'flounder science fiction'. It could potentially be a very unique sub - genre within science fiction that involves themes related to flounders in some way, perhaps in a biological - evolution - in - space kind of story or something really out - of - the - box.
Friendship is a common theme. Flounder is Ariel's best friend in the original story, and in fanfictions, this friendship is often explored further, like how they support each other through tough times.
One popular 'the little mermaid flounder fanfiction' could be about Flounder's adventures on his own, away from Ariel. He might encounter other sea creatures and have to use his wits to survive.
I'm not sure who Ariel is in this context without more information. It could be a unique character created specifically for this 'never - ending story' that has its own set of characteristics and a role within the plot.
Ariel could be any character created by the fanfic author. It might be a mermaid, as the name Ariel is often associated with mermaids in popular culture.
Some might think so because of the out - of - this - world and often zany elements in Harry Potter. Just like in a flounder fanfiction where the author might come up with really strange and unique ideas, in Harry Potter we have things like talking portraits, flying broomsticks, and magical spells. These elements are so different from the normal world that it could give the impression of being part of a more off - the - wall fanfiction.
Ariel is mostly not a real story. It could be from a fantasy world, a product of someone's creativity. There's no historical or factual basis for it to be considered real.
