Q enjoys mixing things up thematically. That's why the music doesn't match the setting. There is a live mariachi band throughout the evening playing your favorite disco hits from the 70s and 80s. Do you ask the band to play something different? They'll nod in agreement and then just play more ABBA.
⬥ Sorry, you can't keep that pretty flapper dress! The outfits will only remain while the characters are at the party. If they leave Carbunkle House, they'll be returned to whatever outfit they had on when they arrived.
⬥ The outfits must be something the character would approve of and be comfortable in. No one will be glamoured into something that they wouldn't find appropriate.
⬥ Q's animal curses only last while the character is at Carbunkle House. If they leave Carbunkle House, they'll revert back to normal. If they leave and come back, they'll be their normal selves again. (But if they annoy Q he might repeat the punishment.)
⬥ No one will be harmed in their animal form. (Q likes animals more than he likes people, after all.)
⬥ Characters with magical abilities can transform their friends back, if they want to. It is up to player discretion as to whether their magic works. Talk to your friends if you want them to help your character out! (Or beg Q for his forgiveness.)
