When Ylvi is captured by Pox to become a maid on Sven's ship, Vic and the Vikings rush to rescue her. While the drakkar catches up with the Pirates, Ylvi creates arguments aboard Sven's ship (she's way too young to be a maid!), and proves she can be a mischievous girl when needed. When the Vikings catch up, Sven thinks he's got the upper hand as he threatens to throw Ylvi overboard. But Vic creates flippers and snorkels and swims near the Pirates' ship to rescue Ylvi as she is dropped in the ocean.
