A group of kids in the small town of Stradale called "The Galactic Builders" were all interested in the wonders of the world. They met every day after school in a shed that served as their base of operations. They dreamed of making a rocket that would take them on amazing trips through the stars. The kids got together because they were all interested in space. Timmy, a curious and creative kid with a big mind, and Emma, a helpful and resourceful girl, led the group. Alex and Lily, who were, were both great engineers. Sammy, who was the youngest member of the group, was good at reading maps and navigating. One sunny afternoon, Timmy found an old treasure map in his grandfather's attic. It was said to lead to the buried Cosmic Crystal, a magical diamond that could make any dream come true. They started looking for the crystal because the idea of using it to power their spaceship was exciting. The Galactic Builders collected trash from the town and turned it into navigational tools, rocket boosters, and the body of the spaceship. While Sammy figured out where they needed to go, Alex and Lily drew plans for the spaceship, trying to come up with more creative ideas than the others.
