I'm honestly not seeing the point of having two home-street "spirits."
When the Magic Rock lived in our game window all the time, he was a constant presence with a quest-managing and feedback providing purpose. Now, he lives on our home street/back yard, and seems very tied to those places. He manages cultivation and expansion. He keeps track of visitors' use of resources on the street.
But we also have botlers. And they live on our home streets. They handle mail and messages and presents. Why? Why couldn't the Magic Rock do that?
The botlers arrived at no cost to us, just like the MR. All of their functions are things that the MR could perform and vice versa. The division of labor seems arbitrary and pointless. This seems like an unnecessary multiplication of entities. It lacks elegance. (Like the mood mechanic, it seems redundant and—even worse—vestigial and uninteresting.)
So, I propose that we combine the function of these two entities and have a Home Street Spirit. There's no reason why they couldn't be customizable (hey, they could even look like botlers!). They would handle concierge/communication, cultivation/expansion, and street management functions.
Why not start off them off with a basic look and then provide for the application of imagination to customize them? Perhaps imagination could also allow for extra-special-powers upgrades for the Home Street Spirit, such as gift-giving, vending, or auto-harvesting and planting.
I recognize that a great deal of effort has already gone into these two game mechanics, but I truly believe that a combined Home Street Spirit would be more useful and appealing, as well as easier to understand.
