He then went on to explain, "We did originally have plans to promote it but we honestly imagined ourselves performing this track on stage.  A music show is usually very fancy and all," and added that "Dinosaur" wouldn't quite fit well with a music program.

With that, Suhyun mentioned, "The key is too high. It's going to sound like a dolphin's screeching cries," and admitted a live performance wasn't viable.
