General

 * This special is devised by each of the stories for the first five Straw Hat Pirates during the East Blue Saga instead of chronologically. Thus, some of events that occurred during the Syrup Village Arc are shown before the events of the Orange Town Arc and after the Baratie Arc.
 * Every arc of the East Blue Saga is shown in the special, though some extremely minimaly:
 * The scene after Luffy beat the Superhuman Domingos, during the Episode of Nami section is from the Orange Town Arc.
 * The scene at the beginning and closing of the special with the Straw Hat Pirates spotting the lighthouse at the entrance to the Grand Line is from the Loguetown Arc.

Episode of Luffy

 * This is the third time the events of the Romance Dawn Arc was animated. The first was the anime adaptation and the second was the Episode of Luffy special.
 * This is however only the second time the origin of Luffy's scar was shown, as it was censored in the anime adaptation.

Episode of Zoro

 * This part is split between Zoro's introduction from the Romance Dawn Arc and his battle against Dracule Mihawk from the Baratie Arc, Making it the only section comprised of two separate arcs.

Episode of Usopp

 * This special shows Mornin, the mayor of Syrup Village, for the first time since the manga
 * Usopp does not appear in a flashback in this arc.

Episode of Sanji

 * Although not directly stated, Zeff is implied to have eaten his own leg as in the manga. In the anime adaptations of the flashback in Episode 26 and Episode 801, the events were censored so that Zeff cuts off his leg when it gets caught in wreckage while diving to save Sanji. However, in Episode of East Blue, these scenes are not shown nor recalled by Sanji. Instead, Sanji simply leaves his sentence incomplete when he sees that Zeff has lost a leg, rather than explicitly asking if he ate it.

Episode of Nami

 * This is the third time the events of the Arlong Park Arc was animated. The first was the anime adaptation and the second was the Episode of Nami special.
 * Nami's section shows a single scene from the Orange Town Arc, her first encounter with Luffy.
 * This is the first accurate anime portrayal of Bell-mère's death scene.
