"Game of Thrones" Season 3 Dragons

Here be dragons!

The newest clip from the "Game of Thrones" Season 3 premiere features quite a bit of dragon action. Those babies are growing up, flying around, catching food, and breathing fire!

The dragons -- shall we call them toddlers? -- are much bigger than when we last saw them. In the Season 2 finale, they looked, head to tail, as long as Dany's arm. Now they almost match Dany's (petite) height and sport huge wingspans.

"They're growing fast," Ser Jorah Mormont remarks. "Not fast enough," Daenerys replies.

Still, at the rate they're maturing, we wouldn't be surprised if one of them was large enough to bear a small child by the end of the season.

In another dragon-tastic trailer, one shot shows a dragon scorching a city wall; in another, all three spread their wings in the sky above "mother" Daenerys Targaryen's army.

"I shall show you no mercy," Dany says, and a dragon breathes a ball of fire into the camera to prove it.

On Twitter, fans are thrilled at the prospect of seeing the dragons more frequently.

Are Dany's dragons your favorite part of "Game of Thrones"?

"Game of Thrones" Season 3 premieres Sunday, 3/31 at 9 PM on HBO.
