After the incident with the Team Aqua agent and with Peeko safely returned to Mr. Briney, Ash and co set sail for Dewford Island. All is not calm on the way there however as a school of Sharpedo suddenly attack Mr. Briney's boat. Not to mention tear up a part of May's new swimsuit. Now how will Ash and co. get to Dewford with all the Sharpedo in the way? Is this going to be like "Jaws" all over again?
