Casey gets out her telescope for a famous starfish, and notices a flash in the sky. She investigates and finds a flying saucer. An alien named Molly from Seaturn is looking for a root that happens to be in Snorkeater-land. On the word ""reward"", Smallweed pops up again and goes into the ship to find treasure. Casey and Molly get the root and the Snorkeaters come after them. Molly helps her out and they go back to the spaceship. They find Smallweed and they accidentally get launched in space! On the way to Molly's planet, a bunch of sea pirates try to zap them out of the air. They get caught in a meteor shower and take a smooth fall. Luckily, they land in front of a gas station and a dance hall. They find a fabled bird fish and Molly needs a bird feather for her potion. They pull off when the crowd gets ruly and Molly tells them that they need some sort of formula for the potion.
