The group, made up of 10 year olds to teenagers, explain: "We spend lots of our time in school but all we think about is dance, we've been together 3 years.
"We dance all the time and it's really tiring but we love it but it doesn't really matter."
The group, from Wales, add: "We miss parties, birthdays, we miss loads, but we don’t care because he love dance so much, nothing's going to stop us. We're just going to do our best and represent Wales the best we can."
They perform an energetic routine to a medley of tracks, but will the judges be won over?
