Cases & Story

Most of these unlock by playing MOUSE's four connected cases — but several are missable, tied to finding each case's mandatory “key clues” and pinning every clue to the evidence board. Search every room with detective sense on before you trigger the next beat, and use case select afterward to clean up.

What it asks

Reach the end credits by completing MOUSE's interconnected cases — the Missing Magician, the Shrew Shortage, Blue Betty, and the finale they all feed into.

How to earn it

  3. If anything is left, clean it up afterward via case/level select.

Pro tips

  • This is the natural end point of a first playthrough — treat it as your cue to mop up everything else for the platinum.

Find every key clue in the Missing Magician case.

How to earn it

  1. In investigation sections, use Pepper's detective sense to highlight interactables, then search every room fully.

⚠ Missable — rushing to the case's end without examining everything can lock you out. Search fully before triggering the next beat, or replay via case select.

So, Whodunit?

Silver⚠ MissableFull guideCollapse

Pin every clue to the evidence board.
TypeSilver
MissableYes
Difficulty2/10

What it asks

Across the game's investigations you pin clues to a cork evidence board to connect suspects and events. This wants every clue pinned, not just examined.

How to earn it

  1. Whenever you pick up a clue, open the evidence board and pin it — never leave one unpinned.
  2. Make the prompted connections to progress each deduction.
  3. Because clues are case-specific, do this in every case before moving on.
⚠ Missable — an unpinned clue in a completed, non-repeatable case can cost you the trophy. Pin as you collect.
