Messy is the robot dog of the Little Robots' world.
Messy is a very playful and energetic dog. He loves to all things dirty and messy and hates being clean. He also does typical dog actions, such as barking at things (like at shadows in Barking Mad) and chewing on other robots' stuff (like Spotty's slippers). Sometimes, Messy can be a bit troublesome to some robots, but he means well in the end.
Scary frequently teaches him tricks and makes shows with him, where he's known as "Messy the Wonderhound".
