"Free Willy" whale (4)

I believe the answer is:

orca

'free willy whale' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for orca that I've seen before include "Cor! a killer whale" , "Large mammal" , "Marine creature" , "Killer at sea" , "Massive killer" .)

I've seen this clue in the USA Today, the Universal, The New York Times and the Family Time.
