Two more "Frozen" characters are coming to Storybrooke! Fans of ABC's fairy-tale drama "Once Upon A Time" will be introduced to Pabbie the Troll King (John Rhys-Davies) and Prince Hans (Tyler Jacob Moore) in Season 4, according to The Hollywood Reporter.

Executive producer Adam Horowitz made the announcement via Twitter on Monday, July 29.

"We're thrilled to welcome John Rhys-Davies to the #OnceUponATime family as the voice of everyone's favorite rock troll- Pabbie! #ThisFall!," Horowitz posted.

"Excited to welcome @tylerjacobmoore to #OnceUponATime as #Frozen's Hans," he added. "Hope you come meet him this fall in Season 4!"

For those who may be a little unfamiliar with the popular Disney characters, Pabbie is a magic beast who rules the Valley of the Living Rock. Just like in "Frozen," Pabbie is "gentle, wise and the source of unexpected insight," THR wrote.

As for Prince Hans, the sneaky character is still on a mission to take over Arendelle. In "Frozen," Hans tricked Anna, Queen Elsa's sister, into falling in love with him. He was eventually banished by Elsa and was last seen imprisoned and on a ship heading back to the Sothern Isles.

According to THR and E! News, "Once Upon A Time's" "Frozen" storyline will take place after the events of the Disney movie. Elsa will be played by Georgina Hiag and actress Elizabeth Lail was cast as Anna. Other "Frozen" characters include Kristoff (Scott Michael Foster). Elizabeth Mitchell was also cast in Season 4 of "Once" but her "Frozen" role has not yet been announced. There were reports that Olaf, the fictional snowman, will not appear in the TV show.

ABC debuted the first footage of Anna and Elsa at San Diego Comic-Con and revealed the premiere episode for "Once Upon A Time" will be titled, "A Tale of Two Sisters."
