The Shirt Tales characters were a Hallmark Cards creation in 1980. The characters turned out to be popular enough to warrant a cartoon, and in 1982, an animated Shirt Tales series began airing on NBC. The characters were basically animals wearing t-shirts. The t-shirts were unique in that they flashed messages relaying the animal’s thoughts. Some of the characters included Tyg Tiger, Pammy Panda, Digger Mole, Rick Raccoon, and Bogey Orangutan. In the cartoon, they lived in Oak Tree Park and used their Shirt Tales Supersonic Transport (STSST) to find adventures around the world. The plush animal toys also had messages on their t-shirts, such as "Day Dreamin'," "Smile" and "World's Greatest."
