In rhyming text, Moby Shinobi and his dog Toby head to the beach for a day of fun, where Moby tries to put his ninja skill to work helping his friends build a sandcastle which unfortunately cannot withstand the weight of even a small ninja--however when a sailboat springs a leak, it is Moby Shinobi to the rescue.

Told in rhyme, Moby Shinobi and his dog Toby volunteer to drive when his friend Jenny's junior race car driver fails to show up, but as usual his enthusiasm ends up in a mess of oil spills, flat tires, and wrong turns--but he redeems himself by repairing the oil leak, and wins the race for Jenny.
