Boodle

Boodle (ブードル, Būdoru) is the mayor of the town that was attacked by Buggy the Clown early on in the series.

A New Life
Boodle was one of several people who was forced to leave their previous home elsewhere by pirates. Having been driving out of their last home, the townsfolk decided to set up the town of Orange Town. Over time others came to the town to live there and it became big. For 40 years the town grew and grew.

Boodle had a odd relationship with one pet store owner who had set up shop in the town. He was an old friend of his and even went so far as to buy dog food from him when times were harsh.

Then one day from out of nowhere Buggy the pirate appeared with his crew. They forced the townsfolk out of their homes and took over the abandoned town. Boodle continued to return every day to feed Chuchu, even though he knew it carried a high risk factor with the pirates there.

Hope
Boodle first appeared when Chou-Chou was being attacked by Luffy for stealing the key to the cage he was in. He explained to Luffy and Nami why the dog was defending the pet store. He also tried to stop Nami from attacking Luffy later after the store was destroyed. .

With the help of Luffy, Zoro and Nami (and you could count the help of the dog Chou-Chou), Boodle is able to defeat Buggy's crew and drive them out of the town, even though he was knocked out by Luffy so he doesn't get in the way.

Later on at the end of the arc, he, along with Chouchou, went out to the dock and thanked the three for what they had done.
