— -- We are counting down to the premiere of the all new Disney Channel movie “Descendants 2.” If you somehow missed the all-out fandom and mania that followed the first "Descendants" movie when it debuted in 2015, let’s get you into the loop. It’s a story about the exiled children of Disney villains who’ve been offered a chance to live among the heroes. Of course, that’s when things go awry.

Here are five things to know before you watch "Descendants 2":

1. New characters will be introduced

Three new villains have been added to the cast to help stir things up. Disney alum China Anne McClain joins the cast as Uma, Ursula’s daughter. Thomas Doherty will star as Harry, son of Captain Hook. And Dylan Playfair will take on the role of Gil, son of Gaston. Together they bring with them lots of mischief and some great laughs.

2. The new songs will get stuck in your head

"Descendants" music videos have amassed more than a billion views already on Disney’s YouTube channels. And now there are several new tunes coming your way in this new film. Be sure to watch out for the performance of “Ways to Be Wicked” and Sofia Carson’s “Chillin’ Like a Villain.”

If there is already a "Descendants" fan in your home, brace yourself for the new tunes to be on regular repeat.

3. Everybody dances

In typical Kenny Ortega (the director of "Descendants") fashion, there’s plenty of singing and dancing throughout the film. This time, everybody in the cast dances. Be on the lookout for a big choreographed number that involves lots of water. It's a great one.
