Tammy Tumbler

Tammy Tumbler is one of the most memorable supporting characters in MOUSE: P.I. For Hire (2026), the noir-inspired first-person shooter developed by Fumi Games. A street-smart young mouse mechanic who grew up in the foster care system, Tammy serves as the backbone of Jack Pepper’s detective operation. After Jack arrested her stepfather during his years on the force, he took Tammy under his wing, and she has stuck by him ever since. She runs Tammy’s Bearings, a workshop in the heart of Mouseburg where she upgrades Jack’s weapons and builds the gadgets that keep him one step ahead of the city’s corruption. Tough, inventive, and fiercely loyal, she is far more than a sidekick. Her personal history gives her scenes genuine emotional weight, and her engineering skills make her indispensable to the story’s momentum.

English Voice: Tammy Tumbler is voiced by Camryn Grimes, a Daytime Emmy Award-winning actress best known for playing Cassie Newman and Mariah Copeland on the long-running CBS soap opera The Young and the Restless. She also has animation credits, including Tina and Record Scratch in Disney’s Hamster and Gretel. Tammy Tumbler marks one of her highest-profile video game roles to date.
