I would like you all to imagine someone sneaking a Bop It into Hogwarts.
I mean it was sold to the public in 1996, so the Trio would be in their 6th year and by Half Blood Prince they need some levity.
Just imagine the possibility of some muggleborn or halfblood having brought several out of sheer amusement, because they want something to distract themselves, and planting them around school.
Imagine some Slytherin prefect finding one and getting the first and second years in on playing with it because Merlin knows things aren’t too fun for them with the in house tension, let alone the interhouse tension.
Ravenclaws poking at one and making a magical version to play in groups between study sessions because they’re all tense as hell and could use some fun– not to mention copying muggle inventions with magic is a great project.
Gryffindors laughing at the novelty of it at first, then they turn it into a competition in the common room– who can keep the Bop it going the longest without messing up. There’s a scoreboard charmed to update in the corner. Ron tried it once to see if he could write to his dad about it, got farther than some and swore up and down the corridor when someone reminded him he had class. He keeps trying and knocking people down the standing. Hermione was doing very well, but Crookshankes helped her hit the button once because she tripped a bit on a rug, and there was an uproar about it being cheating. Harry trying and not being sure what to make of it and then using his reflexes to get kinda good at it, but still not quite catching up to Ron and cheering him on.
Hufflepuffs have been playing with them or placing them around the school in strategic locations that could use some amusement.
