Fight!

A person in a green, spiky, turtle-like costume with a large white letter 'M' on its back interacts with a child in a blue hooded jacket on a city sidewalk, as the child repeatedly pushes against the costumed figure, which responds with exaggerated, playful movements. The scene takes place on a wet, paved sidewalk next to a street with parked cars and a multi-story building in the background.
