The NU'EST boys are saying 'thank you' to their fans through a very special video!

On May 19, the group released a dance practice video for "BET BET" with all five members wearing different hilarious costumes - featuring JR as 'Jeebby,' his parody of 'Harry Potter's Dobby, Aron as 'Noaron,' a puppy, Baekho as a lion named 'Lionho,' Minhyun as 'Hwangsaw,' his version of Jigsaw from the 'Saw' film series, and Ren as an angry avocado fittingly named 'Angry Avocado.' 

The video was made to commemorate the group's first music show win, which occurred on the May 8 broadcast of MBC's music program 'Show! Champion.'

Check out the fun dance video above!
