Shirt Tales are characters that were created in 1980 by greeting card designer Janet Elizabeth Manco and were featured on Hallmark Cards greeting cards. The characters were adapted into a 1982-1985 animated series for television, by Hanna-Barbera Productions, which aired on NBC. Cards Hallmark Cards released the homonymous line of greeting cards with animal characters wearing T-shirts upon which was a message. Those cards were among Hallmark's best sellers at that time, which led the company to team with Hanna-Barbera Productions to adapt the Shirt Tales into a Saturday morning cartoon, which premiered on NBC on September 18, 1982. The card line remained, but it faded shortly after the show left broadcast television in 1985. TV series The animated Shirt Tales cartoon featured Tyg Tiger (in orange), Pammy Panda (in pink), Digger Mole (in light blue), Rick Raccoon (in red), and Bogey Orangutan (in green) (so-called because he spoke using a Humphrey Bogart-style voice). They lived in Oak Tree Park and wore shirts that flashed various brightly lit messages which reflected the characters' thoughts. They spent their time teasing the park custodian, Mr. Dinkel, and battling crime in and out of their hometown of Mid City. They zipped around the world in a vehicle known as the STSST (Shirt Tales' SuperSonic Transport) which could operate as a car, jet, boat, submarine, and other forms of transportation. Though most law enforcement agencies like the unnamed Commissioner knew of the Shirt Tales as crime fighters by reputation, few people seemed aware that they were talking animals—including Mr. Dinkel, whom the group often had to trick to keep their secret safe. Each episode was divided into two 11–minute segments. After the success of the thirteen episodes in Season 1, ten episodes were created for Season 2. However, the show was semi-rebooted and Kip Kangaroo (in light yellow) was added to the cast of characters without context for her joining the Shirt Tales. There is also a difference in leadership among the Shirt Tales, in which for the first season Rick appeared to be the de facto leader, but in the second season is instead Tyg. Several stories in Season 2 either omit Rick altogether or give him a minor role in the story. The second season also added some superhero elements to the dynamic of the group as well, most notably the color of all their T-shirts changing to a bright red color
