Ready to Die

A blue pony lies strapped to a table as a mechanical arm descends with a spinning blade toward its chest, then the scene cuts to the pony's head screaming in terror, followed by a close-up of a red creature with a single eye and a wide grin, then a view of the pony's body being torn open from the inside, revealing its internal organs, and finally a close-up of the pony's head with wide eyes and a gaping mouth in extreme distress.
