The team goes back to the year 1492 to look for the Time Shifter Coconaut, where they find themselves pressed into service for the famous explorer Christopher Columbus upon being fished out of the ocean by his crew. Coconaut is revealed to be assisting Columbus in his navigation. Petra Fina uses this fact to inspire distrust for Columbus amongst the crew and also to steal Coconaut and take command of the fleet where she plans to rename America as Petra-Merica. After escaping from abandonment on a desert island, Flint and his friends rush to set things straight and free Coconaut.
