Well, you could write a fanfiction where a detective is investigating the Pet Shop of Horrors because of some strange disappearances in the neighborhood. The detective starts to suspect the shop owner and the pets, but as he delves deeper, he realizes there's a whole otherworldly reason behind it all. Another plot could be a young artist who finds inspiration in the unique and often terrifying pets in the shop and creates a masterpiece that has a strange connection to the shop itself.
One idea could be exploring the backstory of the shop owner. Maybe he has a tragic past that led him to open this strange pet shop. Another could be a customer who gets a pet that changes their life in unexpected ways, like a small pet that actually helps them solve a big mystery in their town. Or perhaps a story about a group of friends who visit the pet shop together and each has a different encounter with the creepy pets.
A great plot for Pet Shop of Horrors fanfiction could be a story about a journalist who wants to do an exposé on the pet shop. As they interview the owner and observe the pets, they slowly start to question their own sanity. The pets seem to have a mind of their own and the journalist begins to feel like they are being watched not only by the owner but also by the pets. They might also discover that there are hidden rules in the pet shop that, if broken, lead to dire consequences.
Well, you could have a plot where a rare and dangerous pet escapes from the Pet Shop of Horrors and the main characters from Harry Potter have to track it down before it causes chaos in the wizarding world. Maybe there's a pet that can change its form and is being used by a dark wizard to spy on Hogwarts students. Or it could be that a special pet is the key to unlocking a hidden magic in the Forbidden Forest and different characters are vying to get it from the pet shop.
One idea could be exploring the backstory of Audrey II more in - depth. Maybe it came from a far - off planet where plants have a different form of intelligence. Another could be a time - travel fanfic where a character goes back in time to stop the plant from ever being brought to the flower shop.
One idea could be Seymour exploring an alternate universe where Audrey II doesn't have a thirst for blood. He could live a normal life, running the flower shop peacefully. Another could be Seymour traveling back in time to prevent himself from ever finding Audrey II in the first place. This would change the entire course of events in the story.

One idea could be an OC who has a special power like being able to communicate with all the pets in the shop at once. This could lead to all kinds of adventures, like solving mysteries when the pets' toys go missing. Another plot could involve an OC who is a new pet in the shop and has to learn how to fit in with the other pets. Maybe they have a different species - like a magical unicorn - which makes it even more challenging.
One idea could be Blythe's mom discovers a hidden talent of Blythe related to the Littlest Pet Shop that she never knew before.
