While a dangerous battle with the Dark was still raging, Timmy Barnes and Bear Company escaped in the night, at the orders of General Leo. With the help of Armor Division, they cross into the desert, taking a detour to find a secret cache of supplies so they can repair their damaged armor. There they find Desert Troop, a bizarre assortment of creatures that may or may not be just a little crazy. Desert Troop tells them of strange animal behavior in the area—like spiders riding on birds, and snakes eavesdropping on conversations. But at least the Dark won’t find them out in the desert… right? As they say, the best-laid plans often go awry, and there just might be someone lurking about in the desert—a dangerous new villain who has set her sights on Timmy and his friends.
