Milo, Zack and Melissa head to the woods for a camping trip while Zack's parents relax in a nearby spa. Meanwhile, Dakota and Cavendish are taunted by Mr. Block about their supposed excuse to get off of pistachio duty. He tells them to save pistachio plants from a group of red-beaked crows. The duo feel that if they succeed, the pistachions would come back so they decide to have a ditch day. They eventually encounter the crows and attempt to lead them to the pistachio plants. Back at the campsite the trio gets ready for bed. Milo starts to sleepwalk, and his friends go after him.
Dakota and Cavendish lead the crows to the pistachio plants, but they are full from the four Limburger sandwiches Dakota used to lure them with, so they destroyed the plants themselves. Meanwhile, Zack and Melissa chase Milo until he is blocked by a tree. Brick and Savannah see Dakota and Cavendish destroying pistachio seedlings and report them to Mr. Block, who sends them to clean outhouses in the Renaissance. However, he has Brick and Savannah take their old job, much to their frustration. Brick then kicks a rock and hits a bear which chases them. Melissa and Zack return with Milo to the campsite and they collapse from exhaustion. Milo wakes up thinking they stopped him from sleepwalking from the site, only for Melissa to hit him with his backpack.

After their attempt to destroy the pistachio trees, Mr. Block decided to assign them to the even-worse mission, "Cleaning outhouses at the Renaissance", and move their pistachio duty to Brick and Savannah.
The myth that you should never wake a sleep-walker stems from the fact that some people are frightened and react violently in the first few seconds after being wakened, still others are grouchy for several minutes, even a half hour. The truth is that far more people are injured or die while sleepwalking than from waking a sleep walker.
