If there's one thing Disney fans love, it's finding Hidden Mickeys.
In E! News' exclusive sneak peek from The LEGO Group's Frozen Northern Lights (premiering Friday at 8 p.m. on Disney Channel), Elsa's icy powers are again acting up, resulting in some familiar sculptures. "I don't know what's happening to me," she confesses. "This is so strange." Elsa's incident leads to a musical moment that proves it's not easy for her to, ahem, "Let It Go."
Watch the video clip closely to spot Mickey Mouse's cameo.
E! News also has an exclusive photo of Anna, Elsa and Olaf from the TV special.
