(CNN) -- Avery Huffman, a 6-year-old girl, was recently diagnosed with an inoperable brain tumor.
Huffman also happens to be a huge fan of the hit Disney animated feature "Frozen," and her favorite characters is Anna, as portrayed by "Veronica Mars" actress Kristen Bell.
So one can imagine Huffman's surprise when she received a phone call from Bell herself.
Huffman listened to Bell's voicemail, which praised Huffman for being "brave" and a "good girl," all while in character as Anna.
She was even given an offer to become the "honorary princess of Arendelle."
