The New Adventures of Gumby: The 1980s

Gumby discovers a spaceship in a toy store and decides to visit the moon. Upon reaching the moon, his spaceship is destroyed by a meteorite, leaving him stranded and confronted with strange objects that look like rocks, but which sometimes move and sprout eyes. The rock-like moon creatures pursue Gumby to a crater. Looking through a telescope, Gumby's parents discover that Gumby is in great need of help. Gumby's father sets out to rescue him in a fire engine that has a long extension ladder. Using the fire extinguisher, he sprays the moon creatures and takes Gumby back to earth.
