Become the Best Caretaker in Monster Museum
Studio Klafti has officially locked in a release date for Monster Museum: Tidy Up the Collection!, and the charming organization adventure is headed to Steam for PC and Mac on September 30, 2026.
The game drops players into a cozy museum packed with 2,586 adorable monster figurines, but someone has scattered them across the museum. Professor Walt, the legendary collector behind the world’s largest monster museum, leaves you in charge while he’s away. Unfortunately, your mischievous creature companion turns the entire collection upside down, and it’s now your job to restore every shelf before the professor returns.
Gameplay revolves around sorting each figurine by its type and evolution stage, creating the kind of satisfying, methodical experience that fans of relaxing puzzle and organization games will instantly recognize. Every completed collection also unlocks Professor Walt’s hidden research notes, revealing more about the museum’s mysterious legendary monsters.
Players can choose their favorite creature companion before starting the adventure, and each companion brings its own personality to the journey. As you make progress, your companion learns new abilities that help speed up the restoration process, adding a fresh twist to every playthrough.
Best of all, the game keeps the pressure off. There are no timers, no game overs, and no stressful objectives, just a peaceful, rewarding experience built around putting chaos back into perfect order.
If cozy games like A Little to the Left and satisfying collection management are your thing, Monster Museum: Tidy Up the Collection looks like one of this September’s most relaxing indie releases.
