Super Mario Galaxy 2 secret storybook epilogue! Nintendo has quietly added what appears to be a brand-new chapter to Rosalina’s storybook, and most players have completely missed it. In this short, I’ll show you exactly how to unlock the hidden epilogue and trigger the new story content.

To unlock the secret Rosalina chapter, you first need to complete and unlock the final storybook chapter. Once that’s done, simply play any level and collect a Power Star. After finishing, Lubba will notify you that a new chapter has been added—and the storybook will turn white, confirming the epilogue is available.

It’s an awesome secret for fans of Mario Galaxy lore and Rosalina’s backstory.
