I agree that the zookeepers might very well have been intended to be the final dlc as the miscellaneous animals and the party theme was a goodbye sign.
A while back, I thought of a cool farewell pack. World’s fair dlc. I thought of the idea from anno 1800. New vendors or re use Pc vendors with food types from around the world. Perhaps a gazebo or stage where music can be played. A good amount of animals and all in all a way of saying The End.
Scenery: ribbons, advertisement boards, posters, new windows, archways, confetti
Vendors: can’t decide which would be best
