They consisted of two stallions, one of which being the former criminal The Milk-Money Bandit, who drove on a scooter, and snatched chocolate bars from citizens.
Life Before Capture
Capture By LarryBoy
On the grand opening day of the Bumblyburg Pet Shop, the two bandits stole a chocolate bar from citizen Junior Asparagus. When the police department called for help, it began the Return of LarryBoy. The Plunger-Headed Hero pursued the scooter-perched criminals, until they turned a sharp corner in an alleyway, and LarryBoy took back the chocolate bar, and left the bandits to Officer Scooter, leaving the victim with wise words: With Great Chocolate, Comes Great Responsibility.
The bandits were thrown in jail, and were not seen in the series again.
