Few ideas It could centre around a Halloween costume party or festival, that Nick & Judy are either attending or have to disguise themselves as party goers? Or could involve a Zootopia urban legend / ghost story that mirrors a ZPD case? Or maybe a creepy house or mysterious location is the focus?

Nick is Flash’s best man Judy is either a bridesmaid or just a guest (maybe Nick’s +1) Sam is either caterer or just a guest The bouquet toss is so slow, that the flowers don’t go very far (either that or they fly surprisingly high & Judy catches them) The couple give slow but romantic vows
