'Let It Go' From 'Frozen' Is Officially The (Very Fitting) Toddler Anthem Of The Season

While the rest of the country is braving blistering weather in three pairs of socks, kids of the Internet have declared, "Let the storm rage on, the cold never bothered [us] anyway." At least, that's what the lyrics say.

Sisters Maddie and Zoe are the latest pair to take on the hottest (coldest?) song of the minute, "Let It Go" from Disney's "Frozen."

Dad Aaron Mendez set up his girls in a studio -- and they took care of the rest. The duo not only hit the notes in perfect toddler fashion (00:59), they also sang through yawns (1:44) and even a fierce tummy ache (3:47).

We'd say they've done their predecessor, 4-year-old Ella, proud.
