Mouse: P.I. for Hire packs 38 jobs into its noir-soaked mystery, and the ones easiest to miss are the side jobs. There are 14 of them total, each locked to a specific main job, and Behind the Nuts is one that players are reporting they stumbled past without even realizing it existed.
Where Behind the Nuts fits in the full job list
Mouse: P.I. for Hire, developed by Fumi Games and published by PlaySide, structures its missions as "jobs" rather than quests or levels. The game follows detective Jack Pepper as he investigates the disappearance of magician Steve Bandel in Mouseburg, a case that spirals into something much larger.
Behind the Nuts is the side job attached to One Flew, which is job 17 in the full sequence of 38. That places it well into the back half of the game, after players have already worked through locations like the Cheeseball Sub, the far wetlands, and the swamp. By that point, most players are moving at pace and not always stopping to sweep every corner.
Here's the thing: the game has no level select. Once you move past One Flew without completing Behind the Nuts, it's locked out. That's the same rule that applies to every side job in Mouse: P.I. for Hire, but it stings harder this late in the run when you're close to the "Real Deal Gumshoe" achievement.
Why the no-backtrack rule matters so much here
The game is explicit that doors lock behind you as you progress through each level. You cannot freely roam back through areas you've already cleared. This design keeps the pacing tight and the mystery moving forward, but it also means side jobs demand attention in the moment, not later.
danger
Completing all 14 side jobs, including Behind the Nuts, is required for the "Real Deal Gumshoe" achievement. There is no way to revisit missed side jobs without starting a new run.
For players chasing 100% completion, the practical approach is to treat every main job as a checklist item: before pushing through to the next objective, verify whether a side job is active. The pause menu lists all current jobs, so checking it regularly costs nothing.
The full side job picture
For context on where Behind the Nuts sits relative to the other side jobs, here's the complete list paired with their parent main jobs:
Two main jobs, Saltwater Cambozo and Glugging From The Deep, each carry two side jobs simultaneously. That's the highest density of optional content in any single level, so those are worth extra attention during a completionist run.
What this means for players working toward full completion
The "Real Deal Gumshoe" achievement requires finishing all 38 jobs. With no level select and locking doors, the only reliable path is playing through the game with side jobs as a parallel priority rather than an afterthought.
