Character in "Frozen" who says "Some people are worth melting for" (4)

I believe the answer is:

olaf

(Other definitions for olaf that I've seen before include "King and patron saint of Norway" , "King --, cantata by Elgar" , "St ---, Norwegian king" , "Man's name; foal (anag.)" , "Scandinavian monarch" .)

I've seen this clue in The New York Times.
