Mouse PI for Hire Poster Girl Walkthrough
Start Job
You can start Poster Girl after receiving “The Bookeeper” By Tinsel Bros, the main job that takes place in the Western Backlot. After obtaining that objective, head to Tammy’s Bearings behind the Soup to Nuts shop in the P.I. Office area and speak with Tammy Tumbler.
Tammy provides several optional objectives throughout the game, including the Behind the Nuts side job that centers around finding the Mouse PI Gloria location.
Posters Location in Mouse PI for Hire
The posters are about halfway through “The Bookeeper” By Tinsel Bros, just past the section with no floor where you must use Tail-a-Choppa and Grappling Tail. Here is exactly how to reach the posters location:
Look for the Extra with the hat, glasses, and trench coat just after the section with no floor.
Take the stairs just past the NPC and look on the brick wall to find the “Triumph of Willie” movie poster.
Bring the Poster to Tammy
After grabbing the poster, complete “The Bookeeper” By Tinsel Bros. Then return to the P.I. Office area and speak with Tammy inside Tammy’s Bearings to complete the Poster Girl side job and claim your reward: 3 Schematics.
While the reward may feel underwhelming at this point in the game, players pursuing 100% completion need to complete every side job in Mouse P.I. for Hire, including this one.
