Plot
While heading towards the location of the noble summit, the Red Wing Pirates are attacked by a sand shark. Wonder decides to act quickly and attack, but he is instantly swallowed hole by the land shark. In an effort to rescue their crewmate, Lupe and Gajeel attack the land shark. Meanwhile, Entei sleeps and Silvia teases Romeo by unleashing all of the tank's weapons. But she doesn't unleash them on the shark, instead she endangers the crew by messing around with the buttons. Eventually Wonder is able to destroy the landshark from the inside before being freed by his allies.

The crew decides to stop, eat the shark and camp out for the night after being confronted by a few desert bandits, who confirm the extremists are active in the desert. The next day, the crew resumes their journey, and eventually reaches what they believe to be the site of the summit.
