Shirt Tales was an animated cartoon that ran on NBC from 1982 to 1984.
It featured Tyg Tiger, Pammy Panda, Digger Mole, Rick Raccoon, and Bogey Orangutan. They all wore shirts which flashed various brightly lit messages reflecting the characters' thoughts. They lived in Oak Tree Park, and spent their time teasing Mr. Dinkle, the park ranger, 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 just about any other form of imaginable ride.
