Space Cases

One day at an academy, 7 people sneak aboard a mysterious spaceship. The people consist of 5 students, who are Harlan, the athletic leader from earth; Catalina, the Saturnian rainbow-head with a sonic scream; Bova, the negative sour-pus Uranian who can generate electricity; Rosie, the happy Mercurian who radiates heat; and Radu, the Andromedan with super strength and hearing.
