Nintendo has announced that Yoshi and the Mysterious Book, a new side-scrolling platformer, will launch exclusively on the Nintendo Switch 2 on May 21, 2026. The reveal coincides with Mario Day and includes a new gameplay trailer showcasing creature discoveries and platforming mechanics. The game continues the Yoshi series tradition with a storybook art style.
Nintendo unveiled details for Yoshi and the Mysterious Book during a Mario Day celebration on March 10, 2026. Originally announced at the September 2025 Nintendo Direct, the game marks the first new Yoshi platformer since Yoshi’s Crafted World in 2019. It forms part of the Mario franchise's 40th anniversary lineup.
The latest trailer, titled "Yoshi and the Mysterious Book – Creature Discovery!", highlights the game's core mechanics. Players guide Yoshi through the pages of a giant talking book named Mr. E, encountering unusual creatures in strange locations. Key features include discovering and naming these creatures, such as a hoop-mouthed bubble-blowing entity that Yoshi can eat, leading to abilities like spitting bubbles for floating. Other elements shown involve eating apples to power up and accumulating stars to unlock new chapters.
Described as a charming 2D platformer with a unique storybook art style and artistic animations, the game emphasizes exploration and interaction. It is exclusive to the Nintendo Switch 2, with pre-orders now available on the Nintendo Store at £49.99 or regional equivalent. The trailer is initially accessible via the Nintendo Today! app, with broader availability expected soon.
This release narrows a previous spring 2026 window to a specific date, building anticipation among fans of the long-running Yoshi series, which debuted with Super Mario World on the SNES.
