Spanakopita!Dr. Venture asks Billy Quizboy and Pete White to accompany him and Hatred to the yearly "Spanakopita" festival held on the small Greek island of Spanakos, as Hank has a Shallow Gravy concert and Dean does not wish to attend, but Billy's archenemy, Augustus St. Cloud, shows up to ruin the fun. An over-confident Rusty bets St. Cloud the X-1 that he will win this year's "Spanakopita Games". However Augustus cheats and Rusty forces Billy and White to deal with Billy's nemesis. Meanwhile, Hatred suspects there is more to Spanakopita than a simple festival and contacts Brock Samson, who tells Hatred there is nothing to worry about. Hatred eventually learns the truth from the local innkeeper Giorgio, who explains they had accidentally kidnapped a young Rusty while stealing from Dr. Venture's boat. They tried to get a ransom for him but the boat was subsequently destroyed in a battle with Venture's nemesis L. Ron, making them unable to contact Dr. Venture. Upon seeing young Rusty crying, they told him it all was part of a festival which they called "Spanakopita". Rusty, unaware of the deception, returned to the island years later as an adult, as his time there was one of the few happy moments of his childhood. The innkeeper also explains during one Spanakopita, Brock had learned the truth as well and kept it a secret from Rusty, which Hatred decides to do as well. Rusty is doomed to lose the final task and the X-1 to St. Cloud, until Pi Wai saves Billy and Pete White from St. Cloud's trap and accidentally loses all of the man's drachma in the process, with Billy winning. St. Cloud says Rusty will not have another Spanakopita, having bought it from Giorgio, but Giorgio assures Dr. Venture that he will always be welcome and that he simply tricked St. Cloud.
