In a Naruto pranks Hyuuga fanfiction, Naruto might use his typical mischievous tactics. For example, he could use his shadow clone jutsu to create chaos around the Hyuuga compound. Maybe he'd make clones that pretend to be important visitors and then act all silly to embarrass the Hyuuga. It would be a really funny scenario as the serious Hyuuga clan tries to deal with Naruto's antics.
I'm not sure specifically as it could be about all kinds of pranks in a fan - created story. It might involve a character or group of characters playing 28 different pranks on each other or within a particular setting.
One possible arrangement is that two people can sleep on one side and the third person on the other side. Or, they could all lie in a row, with each person having their own space along the length of the bed.
Well, in some fanfictions, Naruto has been known to put salt instead of sugar in Sakura's tea. She takes a big sip and spits it out right away, which is quite funny. Also, he might play a prank where he makes it seem like Sasuke has a crush on Sakura by leaving fake love letters from Sasuke around. It causes all kinds of chaos and blushing between the two of them.
Sakura's reactions can vary. Sometimes she tries to get revenge on Naruto for his pranks. If he plays a prank that makes her look silly in front of Sasuke, like the fake love letter prank, she'll be really mad and try to think of a way to make Naruto pay. Sasuke might pretend not to care, but if the prank affects his image too much, like the hair product switch, he'll give Naruto a cold stare. Kakashi is more laid - back and just watches the whole thing unfold like it's entertainment.
For a more elaborate prank, set up a 'fake treasure hunt'. Create a map with clues leading to a 'treasure chest'. But when the campers finally find the chest, instead of gold and jewels, it's filled with things like old socks, rocks, and silly toys. Another fun one is the 'glow - in - the - dark ghost'. Hang some white sheets with glow - in - the - dark paint on them in the woods at night. When the campers go for a night walk, they'll be spooked by the 'ghosts'.
