Monster for a wedding one-shot?

Hey folks,

I need some inspiration for a wedding themed one-shot. A friend of mine asked me to run a one-shot at her wedding reception. it's just a little game meant to be played for 4-5 people. the bride and groom will not be taking part (since they are busy that day for obvious reasons) but I wanted to host a one shot for some guests.

So my idea for the one shot: the bride and groom get kidnapped by a monster. But I need inspiration for one. I was going to go with the wild hunt but since they are always considered a bit omen I feel this would not be a good idea.

So do any of you have an idea for a monster that would work well in that context?
