I can just imagine my OCs throwing a just dance party.

Ferri, Ostara, and Qahnariin would all be like "yassss let's do it!"
Qahnariin would kick everybody's ass because she's athletic as shit.
Siltafiir would be nervous about it at first, but join in after he sees how fun it is.

Zedge would probably be convinced to do one song, but would just sit in his chair, only moving the arm holding the controller because Zedge don't do that shit.

Seishi... Seishi wouldn't even be in the same room as them. Happiness is natural Seishi repelent.

Of course, Qahnariin and Ostara would try sevral times to convince him to come try at least one, but he'd refuse saying stuff like "an assassin would never" and "only demons would participate in that ridiculous activity."
