What kind of pranks does the cartoon kid pulling pranks usually do?

Well, Cartoon Cat's pranks can range from simple tricks like hiding and jumping out to scare others to more elaborate schemes involving magic or transformation. It all depends on the imagination of the creators.

They often do simple pranks like hiding someone's stuff or making funny noises to scare others.

He might do things like calling random people and pretending to be someone else for a laugh.

Typically, Harry is one of the main ones. He has a knack for getting into and out of trouble with his pranks. Hermione might also be involved in some pranks in a more strategic way, using her vast knowledge of magic to create unique and elaborate pranks. And of course, the Weasley twins are almost always at the center of the most elaborate and chaotic pranks in the fanfiction.

He might replace Sasuke's kunai with candy - shaped ones. It would be really funny when Sasuke tries to use them in a fight or training. Another prank could be that Naruto hides Sasuke's training gear and replaces it with a bunch of candies.

Naruto could enlist the help of his friends like Shikamaru. Shikamaru could come up with a really elaborate plan. For example, they could set up a fake mission where Ibiki thinks he's in charge, but it's all just a setup for a series of pranks. They could have actors pretending to be enemy ninjas who act really silly instead of being threatening. And Naruto could keep popping up in unexpected places during this 'mission' to further annoy Ibiki.

One of the funniest pranks could be that the Kyuubi makes Naruto's clones start singing cheesy pop songs instead of following his commands. Naruto often uses his clones in battles and for various tasks. So when he sends them to attack an enemy, they all start singing and dancing instead. This would not only be a shock to Naruto but also to his opponents. Another great prank would be the Kyuubi making Naruto's body move in the opposite direction of what he wants. So when he tries to jump forward, he jumps backward instead, leading to all sorts of comical situations.

Well, there's a fanfic where they prank Carlisle by making his office look like a disco. They put up disco balls, flashing lights and played really loud disco music. It was hilarious.

Peter could play a really funny prank on the Avengers. He might use his agility to secretly attach some helium balloons to Captain America's shield. So when Cap tries to throw it, it goes all wobbly in the air because of the balloons. And for the Hulk, Peter could create a holographic image of a really cute kitten right in front of him. Since the Hulk is usually associated with destruction and anger, seeing a cute kitten would be a really unexpected and humorous situation.

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.
