TL;DR: A new fox NPC who steals exhibits from your completed museum sections, giving you a reason to keep collecting! Or you can hire Booker and Copper to stop her.

I've had this idea for a new NPC and gameplay mechanic for a while. It's basically a way to keep you fishing, bug catching and diving even after you've completed the museum!

Once you've completed your first museum section, you'll unlock Scarlet, a fox burglar who starts visiting your island and occasionally stealing exhibits! She'll only steal from sections you've fully completed, and only takes fish, bugs or sea creatures that are available during the current month.

You'll then need to catch a replacement and donate it to restore your museum. As a reward, you'd get... I dunno, a badge, exclusive furniture, a load of Bells or sommin! (Nintendo can figure this bit out!) And if you haven't replaced the missing exhibit by the end of the month, a villager will do it for you!…
