Dancing Zombies Location - Dying Light Easter Eggs

Dancing Zombies is an Easter Egg which you can find in the central portion of the Slums, inside one of the big hangar warehouses. In order to activate this Easter Egg you'll first need to talk to Babar who is right next to it (he's marked with a Protect Mission Marker on my map and will be on yours when you get close enough).

Once you've started the Protect Quest you will be able to go inside of the warehouse and begin this event by inspecting the electrical panel on the wall. If you are not currently on this protect quest then you will be unable to activate the eletrical panel.
