You will have Oki on your side this time. Lechku will do pretty much the same thing as Nechku; shoot dark fruit and ice. Defeat Nechku using the same technique used last time. Lechku, however, can freeze time, which allows Nechku to attack. Use a Power Slash to stop Nechku. Lechku will also wield a Nine Strike like Ninetails used. Draw a thunderbolt to it. When they malfunction, uses Oki's ice bow, bite him, pull, then fire. You and Oki will then attack him. Repeat this to defeat Lechku and Nechku.
