It’s time to start freaking out, “Once Upon a Time” fans. ABC has released the first six official promo photos from the Season 4 premiere – and they’re everything that “Frozen” lovers hoped for. No need to wait until the Sept. 28 premiere, because we’ve got the icy images below.

As we previously reported, Season 4 of the hit ABC series will find the fairytale characters in a frightening position. Emma Swan, Snow White, Prince Charming, The Evil Queen, Hook and the others will be forced to “defend themselves against a magical force from the past that’s too unpredictable even for Rumplestiltskin – Elsa, the Ice Queen from Arendelle.”

The first photo simply features Georgina Haig as Elsa from Disney’s 2013 animated hit, “Frozen.” Viewers can recognize her by the signature blonde side braid and sparkly blue gown. But she looks anything but the “unpredictable” force that has the Storybrooke characters frightened.

The second photo may be familiar to some, as it was released on the web a week ago. In the image, Elsa can be seen with her hands on her hips as she looks at Kristoff, played by “Greek” alum Scott Michael Foster. As we previously reported, Kristoff will be the love interest of Anna, Elsa’s sister. Like the Disney film, Kristoff is an ice cutter who hides his feelings behind his “sometimes-gruff demeanor.”

In the third photo, “Once Upon a Time” fans can get a better look at Kristoff … and a reindeer! The pair seemed to be engaged in a serious conversation – but about what remains a mystery for now.

Kristoff, Elsa and the lucky reindeer can be seen in the fourth photo from the Season 4 premiere. The group appears to be inside a stable where Kristoff is feeding the creature some leafy greens.

The fifth photo from “Once Upon a Time” gives fans another shot of Elsa in her sparkly blue gown. However she looks a little less stern than her previous shots.

The sixth and final photo released finally shows Elsa with a smile on her face. Unlike the other images, Elsa doesn’t appear to be in the stable with Kristoff and the reindeer. The white curtains and painted cupboard doors seem to be hinting that she’s in a bedroom – perhaps that of her sister, Anna?

“Once Upon a Time” fans will have to keep waiting for an official photo of Anna. You can see the whole “Frozen” gang onscreen when “Once Upon a Time” Season 4 premieres on ABC on Sunday, Sept. 28.
