Origin
Gumby was started by Art Clokey in 1953. The first 'episode' was a 3-minute short called Gumbasia. It showed moving lumps of clay set to music, and parodied Fantasia. In 1955, Art showed Gumbasia to movie producer Sam Engel, who then paid him for a 15-minute movie called Gumby Goes to the Moon. 

Gumby was given his own NBC series in 1957. Female actress' voiced Gumby. New episodes were added in 1962, and Dallas McKennon became the voice of Gumby.

Characters
Gumby's main sidekick is Pokey, a talking orange pony. His enemies are the Blockheads. They are a pair of human-like, red-colored figures with block-shaped heads. The Blockheads were inspired by the Katzenjammer Kids, who were always getting into scrapes and causing discomfort to others. Other characters are Gumby's dog Nopey.  All he says is "nope".  There is also Prickle, a yellow dinosaur who sometimes acts like a detective with pipe and hat like Sherlock Holmes. Also on the series are Goo, a flying blue mermaid who spits blue goo balls and can change shape at will; Gumby's mother Gumba and father Gumbo.  The later series in 1988 added Gumby's sister Minga and mastodon friend Denali.
