It's nighttime in the city, but Baby Garbage Truck isn't ready for bed! He zips through the quiet streets, searching for someone to play with. He asks Limo to play, but Limo drove a lot and is going back to the parking lot to sleep. Trolley is tired and is heading into the depot for the night. E-Bus needs to recharge its batteries, Sprinkler Truck is going back to the garage to get the water in the tank refilled, and Road Roller is so tired that it's going to sleep on the side of the road. No one will play with Baby Garbage Truck. What's an energetic little truck to do? Maybe the moon has an idea....
