It’s happened twice since then, last day of winter Rosalyn’s house had a frozen slime outside of it. Villagers do not help fight >.> at least that I can tell, but that is literally one of the main reasons I live in this place.
I wonder how they get in? Do they just move across the screen transition? What if they chase you near the edge of the map, will they follow you into town now? That be terrible. There are those large blue slimes and rock golems one space away from Silverpine. Many times I had to use the screen transitions to escape those. It would suck to draw one into town. I'll have to test this at some point.
