One Piece: Straw Hat Theater

Straw Hat Theater is made up of five shorts that aired alongside One Piece episodes 279 through 283 in October 2006. They are based on Oda Eiichiro's side comics that were drawn when he was given three sheets of blank paper by his editor and told to draw anything.
The first short is about Chopper Man infiltrating the lair of the evil Dr. Usodabada. The second short is a news report on what food was like for the Straw Hats before Sanji joined the crew. The third short investigates the hypothetical situation of "if the Straw Hat Pirates were Obahan, who would be the strongest?" The fourth short is about the bosses of the Luffione, Zorocia, and Sanjino families fighting for control. In the fifth short, all of the Straw Hats are carefree monsters.

One Piece

Gol D. Roger was known as the "Pirate King," the strongest and most infamous being to have sailed the Grand Line. The capture and death of Roger by the World Government brought a change throughout the world. His last words before his death revealed the existence of the greatest treasure in the world, One Piece. It was this revelation that brought about the Grand Age of Pirates, men who dreamed of finding One Piece—which promises an unlimited amount of riches and fame—and quite possibly the pinnacle of glory and the title of the Pirate King.
Enter Monkey D. Luffy, a 17-year-old boy who defies your standard definition of a pirate. Rather than the popular persona of a wicked, hardened, toothless pirate ransacking villages for fun, Luffy’s reason for being a pirate is one of pure wonder: the thought of an exciting adventure that leads him to intriguing people and ultimately, the promised treasure. Following in the footsteps of his childhood hero, Luffy and his crew travel across the Grand Line, experiencing crazy adventures, unveiling dark mysteries and battling strong enemies, all in order to reach the most coveted of all fortunes—One Piece.

One Piece Log Book Omake

Interestingly, one of the features that most of the Logs share are the publication of some omakes, an English loanword in Japanese for remakes. Those remake comics are three-page ones that tend to parody other genres.
Those side comics were drawn when Oda was given three sheets of blank paper by his editor and told to draw anything. Animated versions, subtitled as Mugiwara Theater, were broadcasted on October 2006 along recap episodes 279 to 283. They featured omakes released from 2nd to 7th Logs.
Some omakes were released outside of the Logs. They're listed below with the others:
* Blue Databook 4 koma
* The 2nd Log: Report Time
* The 3rd Log: Obahan Time
* The 5th Log: Jingi-nai Time
* The 6th Log: Chopper Man
* The 7th Log: Monster Time
* Yellow Databook: Space Time
* 10th Treasures: Third Year Class SEA Time
* The 10th Log: Märchen Time

Chopperman has starred in the animated New Year's Special filler that aired on December 23 2007.
Episode 369 also featured a special Easter egg referring to Chopperman when Oz suddenly discovered the cockpit in its stomach and called itself "Oz Bomber".
