Linda Gunderson is one of the official mascots of the CGI animation company Blue Sky Animation Studios, the second being Blu around the release of Rio when the company was temporarily renamed "Blu Sky Studios," and the first being Scrat from the Ice Age movies.
Blue Sky Studios was founded in 1987 by some people that worked on Tron. During the 90's, the company mainly focused on television commercials such as Chock Full O' Nuts, Mars, Incorporated and United States Marine and visual effects in many movies.
Blue Sky Studios merged into 20th Century Fox in 1997. Their first feature movie was Ice Age, which was released by 20th Century Fox in 2002. It has since then been solely focused on animated features.
