Tony the Tiger is the advertising cartoon mascot for Kellogg's Frosted Flakes breakfast cereal, appearing on its packaging and advertising. More recently, Tony has also become the mascot for Tony's Cinnamon Krunchers and Tiger Power. He is also famous for his catchphrase "They're greeeeat" at the end of every commercial.
In one of the season one episodes, one of the Pink Panther Flakes (a Pink Panther themed Frosted Flakes cereal) cereal boxes features Pink Panther and Tony the Tiger fighting.
Tony also appeared in a Season 2 episode which featured many breakfast cereal mascots being framed for different crimes. He did not speak unfortunatley.
