Casey is one of the main characters. She has light brown skin and hair in pigtails with two orange bows and a blue cap. She is a machinist and can often offer tech support for the other members of the group. She most likely learned the trade from her father, who runs an auto repair shop called, Palm Springs. She has a crush on Mario, more evident in season 1. She often asks Mario to take her to watch dirt bike racing.
She often feels as the odd one out, as she is only a 5th grader and the guys are all in 8th grade. She often gets mad that the guys don't take her or her ideas seriously enough. But often enough they come crawling back to her, after all other options are exhausted.
