BitBY is Back

The bunny in the backyard came hopping back today. He didn't have any little suitcases with him or anything, but I just know that rabbit is up to something, and I suspect it involves installing a burrow someplace! Does anyone know how I can get rent out of him if he illegally moves in? I've seen him looking suspiciously at one of the storage buildings like he thinks it would be a lovely bunny dwelling.
