Two parts in one matching expansion

The Hidden Treasure of Area Zero is paid additional content for Pokémon Scarlet or Pokémon Violet. It contains Part 1: The Teal Mask and Part 2: The Indigo Disk, two adventures that connect while taking you to different settings. The base game is required. A Scarlet expansion is compatible with Scarlet, and a Violet expansion is compatible with Violet. This version matching is a purchase requirement, not merely a preference about the Pokémon pictured on the listing.

The two-part structure is worth understanding before focusing on any individual creature or item. The Teal Mask introduces Kitakami and its local stories. The Indigo Disk moves to Blueberry Academy and develops a different school-based adventure. They are not two unrelated packages that can be approached as though the second has no connection to the first.

Kitakami and The Teal Mask

The Teal Mask takes the player on a school trip to Kitakami, including Mossui Town and its Festival of Masks. Ogerpon is central to the expansion's imagery and local legend, while new Pokémon such as Poltchageist help establish a setting distinct from Paldea. An unfamiliar place with a smaller community gives this part a different narrative scale from the base game's wide map and three adventure paths.

Nintendo's support instructions say access to this part requires unlocking the Treasure Hunt in the base game. That is more useful than a vague promise that DLC becomes playable as soon as it is purchased. If the content does not appear, check game progress, the exact expansion version, and the console's software updates before assuming the purchase failed. Keep the original save safe while investigating; starting over is not the ordinary solution to a missing DLC prompt.

Blueberry Academy and The Indigo Disk

In The Indigo Disk, the player becomes an exchange student at Blueberry Academy, a school largely located beneath the ocean. Its Terarium contains different environments for Pokémon to inhabit. The contrast with Kitakami is deliberate: one part develops a rural festival setting, while the other uses an unusual school and its constructed habitats. Terapagos is a central Pokémon associated with this second adventure.

The official access requirements are stricter here. Nintendo states that beginning the main story requires completing the base game's main story and The Teal Mask's main story. The Terarium also gives collecting a new structure: support for its environments can introduce returning first partner Pokémon, and completing a substantial Blueberry Pokédex supports additional quests. This makes the regional catalog useful as a set of objectives, rather than merely a decorative list attached to the school.

Part	Setting	Main access requirement
The Teal Mask	Kitakami	Unlock the base game's Treasure Hunt
The Indigo Disk	Blueberry Academy	Complete the base story and The Teal Mask story

Planning a return without spoiling everything

Before revisiting your save, decide whether your goal is story completion, new Pokémon, or additional battle challenges. Those goals overlap but are not identical. A reader looking for a first partner species in the Terarium will need different information from one looking for the next narrative event. Use a location or quest-specific guide when you reach that point, instead of reading a complete story summary merely to solve an access problem.

There is also a separate epilogue with completion conditions and a Mystery Gift item, described in Nintendo's official instructions. Do not treat an old distribution announcement as a universal promise that every reward remains available forever. Check the current instructions and any stated deadlines before making plans around event content.

For collecting context, our Paldea and national Pokédex pages can introduce the species involved. For the product itself, the most important checks remain simple: own the base game, buy the matching expansion, update the software, and satisfy the appropriate story requirement. Those checks prevent more confusion than trying to infer access from the DLC's title or thumbnail.
