Trinket Shopkeepers!

Shopkeepers would appear when you're low on sanity (enough that shadows appear, but don't attack.) - When given a piece of gold, they'll give a random trinket from their theme:

Tropical (SW):

Piggy Shopkeeper under the leaves umbrella

Halloween (Event):

Raincoat Shopkeeper with a Demon tail

What do you think, guys? That way the old trinkets can still be gained in-game. Perhaps they could also give the items they gave back in the event, but maybe just one gold, as they're mostly for decoration.
