As you were roaming the halls with Bubbles, you heard a noise "D-d-did you hear that...?" He asked you, shaking, you nod, you both turn around slowly to see...Bannie....His huge vine arm dragging on the floor as he walked toward you and Bubbles, Bubbles was paralyzed and crying in fear, what will you do? (Also Bannie is stage 5)
