When Denys is invited to Sprout Goat's sleepover, he realizes that he's a little scared about sleeping in a barn and away from home, but he decides to give it a go. Things don't go very smoothly, and they get worse when he realizes he's the only one still awake in the middle of the night, but that's when he smells smoke. There's a fire in the orchard, and Denis overcomes his fear to sound the alarm and help put out the fire. (thetvdb.com)
