Watching the version (as seen on platforms like Crunchyroll or Netflix) ensures:
: Jiraiya summons a special "Scroll Toad" (Gerotora) that holds the key to the Nine-Tails' seal on Naruto’s belly. He discusses the possibility of his own death and instructs that the key should be passed to Naruto if he doesn't return.
: Retains scenes with more blood and violence that were edited for US broadcast.
: Jiraiya successfully infiltrates the Village Hidden in the Rain (Amegakure) by hiding inside the stomach of a toad, Gamagoro.
