HI - Could you offer some guidance on the concept behind the pushmi pullyu dance suggested in the choreography video? The show calls for an animal with 2 heads and one body. The dance on the video has 2 people dancing as a couple, separating completely as well as turning in place. What kind of costume is envisioned to make this work for this character? There is no commentary on the video that might shed light on this as there are with the other 2 numbers.
