What all is locked behind multi player?

I exclusively play this game in single player. I'm not really one for multiplayer games. But I'm also a completionist, and there are collections and achievements I can't get without playing with others :(

I know multiplayer is required for the Basement Library achievements, one of the Fixer Upper achievements, and for the witch outfits in the clothing collection.

Are there any other items/collections/achievements that require multiplayer?
