How to get "Delivery Badge??

Nice find, i searched throughout the entire backyard and only found two different things, #1- The shop in the sewers with rat is now "For Lease" with safetey tape all over it. #2-The town hall has gnome construction workers working on something inside. You can tell by their voices that they are gnomes, and if you peek through the little opennings in the town hall building, you will find a gourd like the one in the multiplayer portals. So theres a possibility of us getting some kind of new mode.
