Even though Tank and Joey were friends now, they still had some issues. When Joey takes Tank to go fishing with his Uncle Mike, they run into all kinds of problems. First they are late, then the fish aren't biting, but even worse, there's a disappearing sailboat in the very shallow Saugus River! Legend had it, there was pirate treasure buried on Dungeon Rock. Three pirates were found, but the fourth--Thomas Veal--escaped and moved the treasure to his cave. Since the fish weren't biting, Joey decided treasure hunting would be more fun. Can the boys find the treasure, or will Veal cause them drama on Dungeon Rock?
