The Martians are small green sentients that live on Mars.
The Journey to Mars
They were discovered by Candace, whom they make the Queen of Mars after she destroys a Mars Rover that they perhaps hated. After they discovered music, they aided Candace in the song, "Queen of Mars". They seem like the perfect friends to Candace, who'd come to Mars because she believed her friends hated her, but they quickly become annoying to Candace, and would not stop fawning over her and worshiping her new royal status. Of course, not understanding English, they didn't understand her asking them to leave her alone.
Ferb, oddly, also has the uncanny ability to communicate with them, even telling them about the complex intricacies of a Science Fair. The aliens quickly became interested with the idea, which results in Candace dubbing them "little green nerds" ("Unfair Science Fair Redux (Another Story)").
Personality and Traits
Every part of their body appears to be a musical instrument, but they had actually never discovered music before Candace showed them what exactly music was. They also seem to worship anything/anyone who destroys the Mars Rovers, perhaps because they don't want to be seen.
The Martians also have the inexplicable ability to meld into one large Martian.
Some of the musical insterments include: Piano key teeth, Bass antenna, etc.
