Well, a great plot could involve Derpy and Dinky finding a magical object. They don't know what it does at first, but as they explore it, they discover it has the power to create beautiful dreams for everypony in Ponyville. However, an evil pony wants to steal it for their own bad purposes. So, Derpy and Dinky have to protect it. This would involve a lot of action, like chase scenes and hiding from the bad pony. It would also show their strong bond as mother and daughter.
One idea could be that Derpy and Dinky go on an adventure in the Everfree Forest. They encounter strange creatures and have to use their wits to get out safely. Another could be a story where Dinky gets lost in Ponyville and Derpy has to search for her, leading to a heartwarming reunion. Or perhaps a plot where they team up to help a new pony in town feel welcome.
Derpy in fanfics is known for her loyalty. She is loyal to her friends, especially to Dinky. She will go to great lengths to protect those she cares about. Her loyalty is a source of strength in the stories. Dinky is often portrayed as brave for her age. She may be small but she is not afraid to take risks. In a fanfic where they explore an old, spooky castle, Dinky is the one who leads the way at times, showing her courage. Also, both of them have a great sense of humor together. They can laugh at their own mistakes and make others laugh too, which makes them very likable characters in the fanfic world.
Well, sometimes in these fanfics, a great plotline is their time - traveling escapades. Since Doctor Whooves is often associated with a doctor - like, intelligent character, he might take Derpy on a trip through time to see how Ponyville was founded. They could encounter all sorts of historical ponies and get into some tricky situations, like accidentally changing an important event in pony history and then having to fix it.
The contrast between their characters. Derpy is known for her clumsiness and sweet nature, while Dr. Whooves has an air of intelligence and mystery. When these two are paired in a fanfic, it creates a lot of potential for interesting interactions.
One idea could be a wedding between two ponies from different tribes, like a Pegasus and an Earth pony. They would have to overcome the differences in their cultures and traditions. For example, the Pegasus might have a flying ceremony while the Earth pony has a more grounded celebration. Another plot could involve a wedding planner pony trying to create the perfect wedding but facing all sorts of comical disasters along the way, like the flowers not arriving or the cake getting ruined.
One idea could be a Beezen character in the MLP world having to adapt to the magic there. Maybe they start off as an outsider and gradually learn to use the magic for good, like helping ponies build better hives or something.
Well, you could write about a time - travel plot in an MLP School of Friendship fanfic. For example, some of the ponies accidentally go back in time to when the school was first being built. They meet the founders and learn about the original intentions of the school. Or perhaps a story where a spell goes wrong and it makes some of the ponies swap personalities. They then have to figure out how to reverse the spell while also learning more about each other. And also, a story about a lost friendship diary that holds the secrets of the early days of the school, and the ponies go on an adventure to find it.
One idea could be that all the ponies from different tribes come together to face a final, great evil that threatens Equestria. They combine their unique magic and skills to defeat it and in the process, they create a new era of harmony where all differences are truly celebrated.
One idea could be that the ponies from MLP accidentally enter the Pokemon world through a magical portal. They team up with some Pokemon trainers to stop an evil team that's trying to use both pony magic and Pokemon power for their own bad deeds. Another plot could be a Pokemon tournament where ponies are allowed to participate using their unique abilities as if they were Pokemon. For example, a Pegasus pony could use its flying skills in a battle like a Flying - type Pokemon.
One idea could be that the ponies from different pony tribes are forced into the Hunger Games arena. For example, the earth ponies might use their strength and connection to the land to find food and build shelters. The pegasi could use their flying abilities to gain a strategic advantage in the arena, like scouting from above. And the unicorns could use their magic for various things like defense or creating illusions to mislead opponents.
One idea could be that Discord causes chaos in Equestria that the MLP characters have to solve in a really wacky way. For example, he might turn all the clouds into cotton candy and the ponies have to figure out how to make it rain again without making a huge mess. Another plot could involve Discord getting his powers mixed up with a unicorn's magic and they have to work together to undo it. Maybe he accidentally gives Twilight Sparkle the power to turn things into random objects every time she tries to use her normal spells.
