The crazy science laboratory - REMAKE! (my au)

There's an unknown entity who kept roaming through the laboratory. Shadow Milk Cookie had described it multiple times. Not knowing it was actually the person he liked. Mr. Pure Vanilla Cookie. Even Mrs. Holly Berry Cookie had bought professional cameras. None of them worked. They were kinda scared but decided to brush it off. Mrs. Pure Vanilla Cookie couldn't control it. He doesn't mean any harm. But there's an entity to controlled his body. (I cannot find perfect images to put.) (YOU CAN BE ANY Y/N I MENTIONED! :D- Silent Salt Cookie, Shadow Milk Cookie, Pure Vanilla Cookie, Eternal Sugar Cookie, Golden Cheese Cookie, White Lily Cookie, Burning Spice Cookie, Holly Berry Cookie, Mystic Flour Cookie, Dark Cacao Cookie)
