Short Summary
Zoro, Nami, and a caged Luffy manage to escape Buggy's crew, and meet a puppy named Chou-Chou, guarding the pet shop of its former master. They are encountered by Mohji the tamer with Richie the lion, and when Richie destroys the pet shop Luffy stands up for Chou-Chou against Mohji.

Long Summary
As the smoke of the Buggy Bomb's explosion clears, Zoro, wounded, picks up Luffy's cage and drags it in front of a pet shop. He collapses near it, barely conscious due to his wound. Luffy spots a small puppy in front of the shop. Nami then arrives and tosses Luffy a key, but the puppy swallows the key and Luffy strangles it to get it back. The mayor then arrives and orders Luffy to leave the dog alone. He brings the wounded Zoro to his house so that Zoro can sleep. The mayor then returns and explains to Luffy about the dog, named Chou-Chou, whose master died. Chou-Chou and his master were very close, but the mayor knows that Chou-Chou must have realized his owner is dead.

Soon, Mohji arrives riding on top of Richie, his giant pet lion. Mohji decides to tame Chou-Chou, but gets bitten instead. Chou-Chou stands up to Richie, attacking the lion, but is quickly batted away. Richie then turns on Luffy's cage and smashes it, sending Luffy flying into a building. Chou-Chou continues to fight against Richie, but takes a battering. Meanwhile, Nami and the mayor run up to Luffy and are amazed that he is still alive. Luffy watches Chou-Chou fight valiantly against the lion, and soon the pet shop goes up in flames, destroyed. Luffy gets angry, and when Mohji and Richie come up to him, he uses Gomu Gomu no Mi Screw to drive Richie into the ground. Luffy, as revenge for Chou-Chou, then pounds Mohji, taking him out with one hit.

Nami and the mayor soon realize that Luffy ate a Devil Fruit, like Buggy, and that he ate the Gomu Gomu Fruit. Mohji returns to Buggy and when Buggy hears of the loss, he orders that the whole town be destroyed. A Buggy Bomb is fired and the mayor's house is destroyed, but Zoro is fine as he wakes up, standing up from the rubble. The mayor decides to go fight Buggy, not heeding the advice of Luffy, Zoro, and Nami. Luffy and Zoro decide to go fight Buggy and his crew as well, and when Luffy asks Nami to join them, she says she'll join temporarily as they share the same causes. Meanwhile, Buggy orders that a second Buggy Bomb be fired, but the mayor arrives and stops it. He challenges Buggy, but Buggy's hand grabs him and chokes him. Luffy then arrives and pulls Buggy's hand off of the mayor as the episode draws to a close.

Trivia

 * The episode was aired on the same day as episodes 7 and 8, so it was an hour-and-a-half-long special.
 * When Boodle told to Luffy and Nami, how the villagers built up the town 40 years, the background is misplaced and a white bar appeared on the bottom and on the right of the image.
 * In the manga Luffy and Nami are told Chou-Chou's story in detail. In the anime it's seen through the dog's memories.
 * The eyecatchers are Luffy and Zoro's, but the music is reversed: Luffy's theme is played with Zoro's eyecatcher and Zoro's theme is played with Luffy's eyecatcher.
