Sunbeam

"That's my uncle's pet, Moonbeam. She's Sunspot's best friend."

- Jet

Sunbeam is the het ship between Sunspot Propulsion and Moonbeam from the Ready Jet Go! fandom.

Canon
Sunspot is the pet of Jet Propulsion. He is a weird Bortronian animal who acts like a dog, but looks like a kangaroo, has a raccoon tail, and bunny ears. He cannot speak, but he uses sound effects to communicate, and is exceptionally talented at everything except acting like an Earth pet. Moonbeam is another pet, and she belongs to Zucchini, Jet's uncle. She looks like Sunspot except she is light purplish-blue. Moonbeam is Sunspot's best friend according to Jet.

In "A Visit from Uncle Zucchini," Zucchini and Moonbeam are coming to visit Boxwood Terrace. Everyone is excited for their arrival, especially Sunspot. Jet describes Moonbeam as Sunspot's best friend, and Sunspot hugs a picture of her. They are going to play a duet together, and Sunspot practices his concertina. A few moments later, Zucchini and Moonbeam do a video call with Jet and the others, and Sunspot and Moonbeam are glad to see each other. They play some music together. However, due to Zucchini's stupidity, he and Moonbeam never do make it to Earth. Still, Moonbeam and Sunspot manage to play their duet over a video call. Mindy tells them that they "make beautiful music together."

In "Uncle Zucchini Babysits," Zucchini actually manages to come to Earth this time, along with Moonbeam. Upon arriving there, Moonbeam and Sunspot hug, only for Moonbeam to act disgusted at Sunspot's dirtiness. The rest of the episode is dedicated to the gang coaxing Sunspot into taking a bath. At the end of the episode, Sunspot is clean and is sipping a chocolate shake with Moonbeam.

In "Space Race," when Team Propulsion meets with Zucchini and Moonbeam, Sunspot and Moonbeam spin around with each other. They also randomly drum their tummies at each other, only for Moonbeam to push Sunspot with hers.

In "Back to Bortron 7," the characters finally visit Bortron 7, the home planet of Jet and his family. They meet up with Zucchini and his family during the "That's How We Roll On Bortron 7," song. Sunspot and Moonbeam dance together at the end of the song. Later, the Propulsions' mission on Earth is in jeopardy when word gets out that they'll be assigned to a new planet, so the team comes up with a presentation about how amazing Earth's water is. This not only gets the Propulsions' mission extended, but also results in them becoming celebrities. When Sunspot is being interviewed, Moonbeam runs up towards him. Sunspot winks at her, causing her to faint.

Fanon
Sunbeam isn't as popular as other RJG! ships, since they don't have many moments, and it doesn't help that Moonbeam inexplicably disappeared from the show in season 2. However, they are both still well-liked characters, and this ship is supported as a result.

Quotes
"Even across the solar system, you guys make beautiful music together."

- Mindy to Sunspot and Moonbeam

Trivia

 * Sunspot and Moonbeam's relationship and motifs make sense, given that the sun and moon are lovers in some world mythologies. For example, the Krachi people of West Africa believed that the sun and moon fell in love, married, and gave birth to the stars. In Guarani mythology, Tupã was the creator of light and his residence is the Sun. He wedded Arasy, the mother of the sky whose home was the Moon.
 * The closed captions for "A Visit from Uncle Zucchini" describe Sunspot's concertina practicing as "romantic" (at about 02:17).
