Widget (1990)

The show focused on a 4ft tall, purple alien from the Horsehead Nebula named Widget who could shapeshift. He and a group of young, human friends, Brian, Kevin and Kristine, would go through a number of adventures to protect the natural environment. Widget is frequently accompanied by the Mega Brain, an extremely intelligent but somewhat clumsy being who appears as a floating head (with a transparent cranium) and floating hands.

The show was produced by Calico Creations to teach children about the dangers of pollution. Each episode would have Widget contending with a villain 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, both heroes attempting to save the Earth from ecological harm.
