Meet Will and Lexi... Will and Lexi were relaxing in their local leisure centre waiting to begin their weekly swimming lessons when they received an urgent signal from planet Zolly informing them there was a ship full of schoolchildren in danger. Inside the spaceship sent from planet Zolly, Will and Lexi stood in front of a large screen and watched a small ship being tossed around in a violet storm. Determined to help the children in danger, Will used his magical space powers to change into a powerful sea-going tug, while Lexi used her magical powers to change into a powerful tug boat captain. Join Will and Lexi in their efforts to help rescue the stricken ship and get the children safely home to their worried parents.
