Hey Arnold!: The Ultimate Collection

Hey Arnold!: The Ultimate Collection is a multi-disc Blu-ray set collecting all 100 episodes of said Nicktoon, as well as both two of its movies and new bonus features with the original cast and crew.

It is mainly similar to the DVDs released by Shout! Factory, but will present the episodes in production order; the "holdover" episodes produced during a specific season will be shown as part of that season as opposed to the season it originally aired within, in some cases undoing continuity errors between the way they were aired and the way they were produced. As with the other Nicktoon Blu-rays, each episode will be restored from the original masters in high-definition.
