In Genova, school is finally out for two Underdogs, Luca and Giulia, who are both more than excited to go back to Portorosso and reunite with Alberto. But as they make a return to the town, so does someone else who they thought was out of the picture for good....who Alberto first knew him as Signor Vespa.... After the trio hears a rumor going around town that Ercole is planning the biggest sea monster hunt ever known to history, the Underdogs are Portorosso's, better yet Italy's, only hope of keeping the sea monster species alive... Art is Not by me.
