Take a look at Casey and Lacey Nicefolk and you’ll see two regular, all-American kids.
But these brother-and-sister twins have a secret. Hidden in the family barn is the most magical-and coolest-gadget unknown to man: a mystical box that can turn any small object into a life-size replica.
So they dream up a plan to turn a toy boat into the life-size Hotsy Totsy and enter a national boat race. With their dog, Floopy, along for the ride, the twins zip up to San Francisco, ready for excitement.
But this is no ordinary boat, and this is no ordinary race. Casey and Lacey must work together in a nautical adventure that turns into a risky race to the finish line!
