Tammy Tumbler is a sweet little mouse who gets easily excited when she meets celebrities. Luckily for us at Mouse: P.I., her starstruck nature keeps bringing us new cases to solve!
You won’t encounter this mission until later in Mouse: P.I., but it’s definitely worth doing when it becomes available. The reward you get for completing it is particularly good!
Action!
Starting the Poster Girl Side Job

Later in the game, you’ll start a major quest called “The Bookkeeper” from Tinsel Bros. When you get this quest, head to the basement of Tammy Tumbler’s shop to find her. You’ve probably been there already, but if not, it’s located right behind the Ammo Shop, near the P.I. Office.
If you speak with Tammy, she’ll request that you find a movie poster while you’re exploring the Western Backlot on Tinsel Avenue. Completing this task will start a side job.
Head on up to the Western Backlot, and the next job is under way.
How to Complete the Job
Hello everyone! Welcome to the Old West. This is a side task that you’ll complete naturally as you progress through the main story. You’ll need to collect a specific item – Tammy’s favorite poster – along the way. Keep playing as usual, and you’ll get there!
Okay, so you’ll eventually come across this really cute movie extra – they’re dressed up as a detective, just like Jack! And that’s where you’ll find the poster for Tammy, so keep an eye out!
If you look just behind and to the left of the person, you’ll notice a poster on the brick wall!
The Duke Ahmed poster is our treasure, so yank it off the wall, and we’re all done here.
Just a reminder that you still need to finish the main task and return to the P.I. Office, but you’re probably already aware of that.
Rewards
After you return home, talk to Tammy again and give her the poster. She’ll reward you with three blueprints for making weapons!

Honestly, this is likely the most worthwhile side job reward in Mouse: P.I. Since you’re already near the B.A.N.G. desk, you should definitely check what upgrades are available! The schematics Tammy gave you are enough to improve one of your weapons to Level 2, so now is a perfect time to upgrade your favorite!
If you haven’t leveled up the James Gun yet, do it. It’s the best, obviously.
