Nintendo adds free Storybook chapter to Super Mario Galaxy 2

Nintendo used a small content update on Super Mario Galaxy 2 to do a much bigger catalog-management job. The company added the fifth chapter to the twin Lumas’ Storybook on April 29, and it did so without turning the game into a relaunch or a remake. The new chapter is free, opens only after the first four chapters are already available, and appears once a player clears any galaxy and earns a Power Star. Nintendo also said the chapter comes with new music in Nintendo Music.

That combination matters because it shows how carefully Nintendo still tends its older software. A single chapter does not change the core game, but it keeps Super Mario Galaxy 2 moving in the company’s live ecosystem instead of leaving it frozen as a back catalog item. The same campaign tied into Nintendo Switch Online, where members could redeem icon elements for Super Mario Galaxy and Super Mario Galaxy 2. Nintendo had already rotated Galaxy-themed icon waves in late March and April 2026, which made the Storybook addition feel less like a one-off bonus and more like another turn in a longer visibility plan.

For the people who build and ship Nintendo software, the update is a reminder that small changes still carry real production weight. A chapter has to match the tone of the original Storybook, fit the game’s pace, survive localization cleanly, and land without breaking the quality bar that still defines the Mario brand. The work also stretches beyond game development. Nintendo Japan said related My Nintendo Store and Nintendo eShop promotions ran through May 31, while a separate B-R 31 Ice Cream collaboration tied to Super Mario Galaxy ran through May 7 in Japan. That is the kind of cross-team coordination that keeps legacy IP from going stale.

The timing is hard to miss. Nintendo has been building Galaxy visibility around The Super Mario Galaxy Movie, which it said opened in U.S. theaters on April 1, 2026, and which it has described as inspired by the Super Mario Galaxy games. Shigeru Miyamoto introduced the film’s title as Nintendo keeps one of its most recognizable worlds active across games, rewards, retail promotions and film. The Storybook chapter is modest on its face, but it shows how Nintendo can extend the life of an older game with a low-cost update that keeps the property culturally alive.
