The planet Z Galaxy is located in a distant galaxy in the universe. It is larger than Earth's moon but has little land mass and an arid, dry surface without an atmosphere, making it impossible for human life to survive there. However, small, yellow, friendly beings do live there. They have three fingers on each hand and four pairs of feet. They have three eyes that are green and large. Their cities contain small, colorful houses with round windows and triangular doors. The beings live under a large palace decorated with frog figures and ruled by the generous and nice but fat and gluttonous King Z-Xy.
