Appearance of the Dancer

Background

When the bridge comes, the dancer is sent to the same room in the verses, except with opposite colors. The pink box and floor are now bright orange, with the box just being out of thin lines flashing every few seconds, then sent to the mid-chorus part of the background, the repeats the background from the chorus.
