Main • Lunar Jim (Benny Zelkowicz), the main protagonist. He is an adventure- and mystery-loving
astronaut with a blue spacesuit and is curious about his surroundings. • Rover, a robot dog, who is always by Jim's side. Rover likes to play fetch and always helps Jim on his lunar missions. He speaks only in beeps and Jim and T.E.D are the only ones who can understand him. • Ripple (Gil Anderson), the African-Canadian engineer on the moon and is the only female with a red spacesuit until Skye joins. She is always coming up with new inventions to help Jim and often helps him on his missions. She drives the Scooter. • Eco (Jim Fowler), the farmer with a green spacesuit on the moon who works in the Eco dome growing plants and raising the animals. Eco loves to collect rocks and plants to study and help Jim. He doesn't typically go on missions because he is far too busy farming in the Eco dome. He usually drives the Hopper. • T.E.D. (Technical Equipment Device) (John Davie), a humanoid robot. He is the clumsiest on the moon and his clumsiness creates some simple
slapstick comedy. He is somewhat paranoid, being afraid of many non-existent things. However, he is quite smart and sometimes solves the problem in the story, though much of his main plot elements involve him being completely arrogant. T.E.D. represents a child and, essentially, the show's target audience. • Pixel (Kristin Bell), the computer that helps Jim and his friends find things on the lunar surface and tells them their jobs for the day. • Daisy, an anthropomorphized cow. Lunar Jim and his team get their milk from Daisy. • Delores, an anthropomorphized chicken who yields eggs for the team. In the second season, three additional characters were added to the show: • Skye, a young trainee astronaut with an orange spacesuit who comes to Moonaluna for "hands-on" training. • Yik Yak, a turtle-like alien who speaks in rhyme. He visits Jim and his friends often, but his visits usually result in some sort of unintentional problem. Although he only speaks in season 2, he does make a cameo in the first season. • Zippity, A space mailman who sounds like a robot, but is never described as such.
Supporting In the TV show, there are minor characters who make an appearance, and cause some trouble. • Colby the Collector – Used to collect objects on the Moon to study. He makes more than one appearance and was he sent on the Moon before Jim and his friends arrived. • The Garden-bot – Built by Ripple to help Eco garden, but malfunctions and destroys all the plants. • The Lunar Worm – An
anthropomorphic worm that lives in a compost crater who eats the peels of fruits and Jupiterbugs. • The Fluffies– A small species of animals on the moon who reproduce on the double. They are sometimes seen in the background of a few episodes. ==Setting==
