Queen who appears in "Olaf's Frozen Adventure" (4)

I believe the answer is:

elsa

(Other definitions for elsa that I've seen before include "Famous lioness" , "Lioness (born free in Kenya)" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Big cat" , "Girl" .)

I've seen this clue in the LA Times.
