Basically marble would get upset that the new guy in the circus likes pippy more than him. So to prove that pippy was worse than him he'd lock the two in a room. Without food. Pippy would eventually start to get hungry and without his substitute food for meat his feral instincts would kick in..kill and eat 😋

So basically you'd have to try and survive while looking for a way out

Y'know eventually,,it would probably become a kill or be killed situation for the persons oc 🏃‍♀️💨
