Revision 1

The Pocket Dimension is a self-contained area in Bloomwalker that the player reaches through a door inside the Moving House. The player constructs buildings, arranges facilities and decorates it, and the game's companions live and work there. Netmarble introduced it by name in September 2026, when the Tokyo Game Show 2026 trailer gave the first look at it.

Names

What It Is

Netmarble's September 2026 press release describes the Pocket Dimension as a special, self-contained space where players construct buildings and freely customize their surroundings. The Steam store page lists building structures, arranging facilities and decorating as the activities there. The PlayStation Store listing says the space behind the door unfolds far wider than the house looks from outside, and that players can build useful facilities and decorate it however they like.

Netmarble's release presents the Pocket Dimension as the game's housing feature, and the Japanese and Korean releases describe it the same way, as a space for crafting and housing that the player gradually develops into a home.

Companions in the Pocket Dimension

Familiars and higgledies live in the Pocket Dimension. According to the Steam store page they eat, sleep and work there, and their presence gradually turns it into a busy home. The PlayStation Store listing ties its growth to the higgledies: the more of them gather there, the larger and livelier the space becomes. Netmarble's release says players develop the space together with familiars and higgledies.

The facilities built there are part of Crafting. Familiars share formulas for new facilities as friendships deepen, and higgledies bring in the materials those facilities process.

Earlier Descriptions of the House Interior

The idea of a large space inside a small house predates the name. In a gamescom 2025 interview, Park Ki-bin of Netmarble Neo said the house would be expanded through a magic door that enlarges the interior instead of the outer walls. An Xbox hands-on preview of the gamescom 2025 demo described the inside of the house as a celestial-themed bedroom, bigger inside than out and entered with no loading screen. Netmarble has not said whether that demo interior is the same space as the Pocket Dimension.

What Has Not Been Announced

As of September 2026, no official source lists specific buildings, facility types, decoration items, size limits or how the space expands beyond growing as more higgledies arrive. Whether other players can visit or build in someone's Pocket Dimension in co-op had not been stated. The 2025 co-op plan mentioned friends decorating homes together, and the current store listings are summarized on Multiplayer and Co-op.
