Cast of 'How to Train Your Dragon 3' on dragons as emotional support animals

Once, twice, and three times as charming! "How to Train Your Dragon" is back with the third and final installment to the film franchise, and this time its all about "The Hidden World."

We get to go on another adventure with Astrid, Hiccup, and Toothless to keep peace and order amongst the Dragon/Human Utopia!

Speaking of adventure, I visited Dreamworks to sit down with the cast: Jay Baruchel, America Ferrera, Craig Ferguson, and Toothless! (Yes, that's right TOOTHLESS, too).

I asked the cast about the possible perks of training your Dragon to be an: emotional support animal!

Craig Ferguson told me people "would be happier, and there'd be less traffic in LA."

We also spoke about what their "Hidden World" is when they aren't working! Jay shares that he has a "bat cave" and America told me that after becoming a Mom, there's really isn't much of a hidden world.

Craig Ferguson settles what noise a dragon makes once and for all! Want to hear it? Then watch our interview!

You don't want to miss all the fun we shared talking dragons, hidden worlds, and more.

"How To Train Your Dragon: The Hidden World" flies into theaters Friday.
