The Fierce Canine Army is granted a day off, yet Norakuro has no home to return to. After stopping at a yakitori (fried chicken) shop for a drink, he heads to the park for a short nap. Just then, soldiers from the Mountain Monkey Army, who have stolen some secret documents, make their appearance, and Norakuro gives chase. When the Mountain Monkey troops seem to have escaped in a hot air balloon, Norakuro, as a last desperate measure, climbs into a tube designed for launching fireworks and blasts himself right into the balloon. He retrieves the stolen documents, but the plot unfolds in an unexpected manner.
