Actress Sofia Vergara, who gave voiceover in 'Happy Feet Two', says she deliberately asked for a smaller role as she was reluctant to give her voice for the movie.

"I knew it was a small role when I did it. It was my first time doing a voice for anything, so I didn't want it to be a big role because I didn't want to not be able to cope with it," contactmusic.com quoted her as saying.
