Katy Perry's device "malfunctions" and almost kills members of the audience. The butterfly she is flying on is also oddly ugly. But pay attention to the lyrics as it happens:
>I got the eye of the tiger, a fighter
>Dancing through the fire 'cause I am a champion
>And you're gonna hear me roar
It sounds like the victims are entering hell and the devil is "introducing" himself.
