From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Charmy usually patrolled on a dirt bike.
When Charmy first arrived at Penguin Village, he ended up arresting almost half the town for extremely minor crimes. When he was about to arrest a Gorilla for picking his nose, Arale Norimaki showed up holding a stick with poop on it. Charmy was scared of her because she was holding poop on a stick and she chased him through town into the police station, breaking the walls and letting all of Penguin Village's residents free again. After being chased all night, Arale managed to put the poop on Charmy's head.
