you come home one day and see all of your Fumos are scattered around the house. You picked them all up and place them back in your room. You notice movement and low voices as you pick each Fumo up but you shrugged it off. As you picked up Reimu and Cirno and placed them all back in your room they started walking and singing

turns out the Fumos were bored and wanted to do something. They also didn’t move because they wanted to see where you would take them
