Sisi Roll

Sisi Roll (シシロール) is the sub-boss in Clown Man's stage in Mega Man 8. It looks like a giant bouncing disk with a grinning lion's face. It bounces around and will either shoot miniatures of itself or let loose the Rompers that latch on to Mega Man.

Sisi Roll also appears in Magic Man's stage and in Dr. Wily's stage in Mega Man and Bass; it's main function is to destroy sections of the floor to help the player progress further, but it will still be a danger unless the player destroy it.

Trivia
Like the Sisi Truck, Sisi Roll is based on the Shishi lion statue.
