Stretchmo 3DS (USA) DLC CIA is the downloadable CIA package for Nintendo's 2015 puzzle-strategy title on the Nintendo 3DS family of systems. Developed by Intelligent Systems and published by Nintendo, Stretchmo (known as Fullblox in some regions and Hiku Osu in Japan) asks you to pull, push, and stretch blocks to guide a cube-shaped character named Mallo to the goal. This USA release bundles the base game CIA plus the DLC CIA, so you can access the full set of puzzle worlds in one place. The files are intended for consoles running Custom Firmware, and the base game package is roughly 88MB.

If you keep a homebrewed 3DS in your rotation and want a compact, charming puzzler that plays well in short bursts, Stretchmo is a natural fit. It is not a fast-twitch action game; it is a deliberate, logic-driven experience that rewards planning. Below you'll find the technical specs, download buttons, gameplay details, and practical guidance for installing the CIA files.

What Stretchmo Actually Is

Stretchmo is a 3D puzzle game built around a single, elegant mechanic: you grab the edges of colored blocks and stretch or compress them to create paths. Mallo, the same blocky protagonist from Pushmo and Crashmo, returns, and your job is to reach the goal flag at the top of each structure. Because blocks can be pulled outward, pushed inward, and rearranged, every level becomes a small spatial reasoning problem. Some puzzles hinge on a single clever pull; others demand a sequence of moves that you'll want to plan before you commit.

The 2015 release date puts Stretchmo late in the 3DS lifecycle, and it shows in the polish. The game was designed as a free-to-start title on the eShop, with additional puzzle packs sold as DLC. That structure is exactly why this download includes both the base game CIA and the DLC CIA: the DLC contains the extra worlds and puzzle sets that expand the campaign well beyond the starter content. If you install only the base game, you'll have a limited set of puzzles. With the DLC package installed alongside it, the full roster of worlds opens up.

The game is played with the 3DS's stereoscopic 3D effect in mind, and the depth helps you judge how far a block has been pulled. You can also play in 2D if the 3D effect bothers you. Controls are straightforward: you move the camera, select a block edge, and drag. The challenge comes from the puzzle design, not from the inputs.

Key Features

• Stretch-and-pull puzzle mechanic: Grab block edges and extend or compress them to build a route for Mallo to the goal.
• Full DLC puzzle worlds: The included DLC CIA adds the extra puzzle packs that expand the campaign beyond the free starter set.
• Intelligent Systems design: Developed by the studio behind Pushmo and Crashmo, so the puzzle logic is consistent with that series.
• 3D depth support: The stereoscopic effect helps you read block depth; 2D play is also supported.
• Short-session friendly: Levels are bite-sized, making the game easy to pick up for a few puzzles at a time.
• USA region CIA: Packaged for the USA region, with English language support.
• Compact file size: The base game package is about 88MB, with the DLC package around 55MB.

Pros & Cons

Pros

• Clever, original block-stretching mechanic that stays fresh across many puzzles.
• Includes the DLC CIA, so you get the expanded puzzle worlds rather than just the starter content.
• Small download footprint (88MB base, roughly 55MB DLC) that fits easily on a 3DS SD card.
• Backed by Intelligent Systems' track record with the Pushmo family of puzzle games.
• Well suited to short play sessions and portable play.

Cons

• Requires a Nintendo 3DS with Custom Firmware; it will not run on a stock system.
• CIA installation is not a one-click process and assumes you already know your way around FBI, DevMenu, or BigBlueMenu.
• The game is a slow-burn puzzler, so players looking for action will find the pace deliberate.
• This is a USA-region package with English only, which limits it for other regions and languages.
• No numbered version is supplied for this release, so you cannot compare build numbers directly.

Installing the CIA Files

These files are CIA packages, so they install on a Nintendo 3DS running Custom Firmware. The base game is packaged as SCRTCHMO-USA-CIA-(eShop)-Ziperto.rar and the DLC as SCRTCHMO-USA-(DLC)-CIA-Ziperto.rar. Extract both archives first, then copy the resulting .cia files to your console's SD card. You can install them with DevMenu, BigBlueMenu, or FBI. Install the base game CIA first, then the DLC CIA, so the add-on content registers against the correct title. Make sure the .cia files sit in a folder you can navigate to from your installer.

For extraction on Windows, use WinRAR or 7-Zip. Keep your extraction tool updated, because older versions sometimes misread archives and prompt for passwords that do not exist. There is no password on these files. If an archive reports as damaged or throws a CRC error, re-download it rather than trying to force the extraction.

Trust Signals and Version Freshness

The uploader is listed as Berry, and the article date is June 6, 2021. No numbered version is attached to this release, so treat the build as the USA eShop CIA package rather than a specific patch level. The game itself dates to May 13, 2015, and it is a finished retail-era release, not an early-access build, so there is no ongoing patch cadence to track. What matters more is that the base game and DLC packages match: install both from the same source to avoid mismatched content.

Publisher details are clear: Nintendo published the game, and Intelligent Systems developed it. That provenance is useful when you are deciding whether the puzzle design is worth your time. If a link is dead or a file is missing, use the reupload request process rather than hunting for random mirrors. And if you like the game, buying it supports the developers.

Who This Is For

Stretchmo suits players who like logic puzzles with a physical, spatial twist, and who already have a homebrewed 3DS set up. It is less suited to anyone expecting a plug-and-play experience on a stock console, or to players who want fast action. If you have enjoyed Pushmo or Crashmo, the design language here will feel familiar. If you are new to the series, Stretchmo is an approachable entry point because the core mechanic is easy to understand even when the puzzles get tricky.

Notes Before You Download

• For help with multi-part RAR archives, check the FAQ section rather than asking in the comments.
• Update WinRAR before extracting; old versions can falsely request passwords.
• There is no password on any game file uploaded here.
• If an archive shows as damaged or gives a RAR CRC error, re-download it.
• For broken, missing, or dead links, submit a reupload request.

Decrypted ROMs can also be played on PC with the Citra 3DS emulator if you prefer to play on a larger screen.
