Widget (also known as Widget the World Watcher) is an animated children's television series created by Voltron creator Peter Keefe, directed and produced by Tom Burton of Zodiac Entertainment, which debuted in syndication on September 29, 1990.^[2] The series ran for two seasons; in the first season (1990), it aired once a week (usually on Saturday or Sunday), and in the second season (1991), the series expanded to weekdays. The show featured environmentalist themes and was recognized by the National Education Association as recommended viewing for children.^[3]

The show focused on a short purple extraterrestrial from the planet Widget who could shapeshift by spinning like a spinning top into different forms. He and a group of young human friends - brothers Kevin and Brian, and their teenage sister Kristine - protect the natural environment from those who wish to plunder or harm it. Later on they are joined by fellow shapeshifter Half-Pint, Widget's mischievous and overly-curious cousin. Widget is frequently accompanied by the Mega Brain, an intelligent but somewhat clumsy being who appears as a floating head (with a transparent cranium) and floating hands.^[4]

The show was produced by Calico Creations to teach children about the dangers of pollution. Each episode would have Widget contending with a villain from either Earth or outer space wishing to exploit Earth's environment or natural resources, like Dr. Dante, Mega Slank, and his evil twin, Ratchet. In this respect, Widget, the World Watcher is very similar to Captain Planet and the Planeteers and Toxic Crusaders, as all those heroes attempt to save the Earth from ecological disaster. As in those series, Widget occasionally fought against malicious entities spawned by copious pollution. For example, in one episode Widget battled a fellow shapeshifter; a sentient but hostile life form, disguised as a toxic ooze/slick, who was contaminating Earth's beaches and oceans.

The TV series ran for 65 episodes: 13 in the first season, and 52 in the second season. The animation for the show was produced by South Korean studio; Sei Young Animation.
