Robin is safely hidden on his Grandfather’s yacht, but for how long? As Marsh and his thugs try to find him Robin overhears enough of their plans to understand exactly what’s going on. Will he be able to save the day, or will he be discovered before he can put his plans in motion? Plus, in today’s Important Message, Billy’s imagination is soaring thanks to the Swell Prize in specially marked cans of Bat-Supe!
