Fanfiction about Harry Potter pranks on Snape: What are some interesting scenarios?

In some fanfics, the 'pranks bashing' might involve the teachers getting fed up with the constant pranks. So, they come up with their own clever ways to stop the students from pranking. Professor McGonagall could use her transfiguration skills to turn all the prank items into harmless objects. This would not only put an end to the chaos but also teach the students a lesson about respect for the school environment.

In the 'Harry Potter Pranks Everyone' fanfiction, there could be some hilarious pranks. For example, a student might use a charm to make the Great Hall's ceiling show embarrassing memories of the teachers. Another prank could be to magically swap everyone's voices, so that when they talk, it comes out as someone else's voice. There could also be a prank where the Hogwarts Express gets diverted to a completely different location, and the students end up in a strange magical place full of odd creatures and unexpected challenges.

One interesting scenario could be when Harry uses a clever spell in a new and unexpected way during their exchanges, catching Snape off guard. For example, he might use a transfiguration spell to transform something in the classroom into a distraction while he makes a quick escape from Snape's scolding.

One scenario could be that Snape holds Harry Potter captive to protect him from a greater threat that he's aware of but Harry isn't. Maybe he has learned of a new dark wizard's plot against Harry and by holding him, he can keep him in a magically protected area until the danger passes.

A really funny prank could be where a student's quill is jinxed to write only in limericks. So when they're trying to take notes in class, instead of normal writing, it comes out as comical rhymes. This can be a source of great embarrassment, especially if they don't notice right away. Also, pranks with vanishing ink on important parchments are quite common in fanfiction. The victim thinks they've written important information, but it all disappears, leaving them frustrated and others amused.

One interesting scenario could be that during detention, Snape makes Harry clean all the potion bottles in the dungeon while lecturing him about the importance of precision in potions. Harry, in turn, discovers an old, forgotten potion recipe among the bottles and Snape is grudgingly impressed.

One prank could be Harry using magic to make all of Dudley's clothes two sizes too small overnight. Another might be making the Dursleys' living room furniture float whenever they try to sit down. And he could also use magic to make the food on their table turn into slugs when they're about to eat.

Perhaps they are both transported to an alternate dimension where they have no prior grudges. They have to work together to find a way back home. In this new situation, they learn about each other's strengths and weaknesses without the baggage of their past in Hogwarts, which leads to them getting along.

One scenario could be Snape using his wand to communicate with the dead. Maybe he discovers a spell that allows him to use his wand as a conduit to speak to Lily Potter. This would add a whole new layer to his character, as his love for Lily was a major driving force in his life.
