"I got a phone call from George Miller [the director] asking me to play this role. We sat down and he showed me on his computer a documentary-type montage sequence of real penguins swimming, in an Esther Williams synchronized sort of way, and doing things I have never seen them do. Then he explained his vision of the film, asked me to read the script and to voice the character. I was cast a little bit later, and he let me do the singing as well!"
