Irma’s Secret Diaries are a type of hidden collectible in TMNT: Shredder’s Revenge that players must find to complete Irma’s side quest. To start this quest, the protagonists must locate Irma on the Streets of New York during “Episode 2: Big Apple, 3 PM.” During this mission, the Ninja Turtles will pass by Allan’s Car Wash, a background shop next to Channel 6’s television store. Fans can recognize this location by the large purple car sticking out of its open garage. Smash down the front door of the apartment directly to the right to find Irma. Players can visit her apartment and accept her request after completing “Episode 2.”

TMNT: Shredder’s Revenge – How To Play With Friends

Irma’s First Secret Diary Location

  • After finding Irma in “Episode 2: Big Apple, 3 PM,” continue down the streets until reaching a large elevated wooden platform. In the area directly to the right, break the mailbox to discover the first Secret Diary in TMNT: Shredder’s Revenge.

Irma’s Second Secret Diary Location

  • During “Episode 4: Rumble In The Zoo,” players will pass by many animal habitat exhibits, one of which is a pool with hippos and giraffes. On this road, players will find a red fire hydrant beside a bench and garbage bin. Smash the trash can to get Irma’s Diary in TMNT: Shredder’s Revenge.

Irma’s Third Secret Diary Location

  • While exploring the underground underpass in “Episode 5: King Of The Spill,” the Ninja Turtles will get ambushed near a moving escalator and a stairwell. In this room, two brochure stands will sit near the wall at the top of the screen. Break the stand on the right to get the third Diary.

Irma’s Fourth Secret Diary Location

  • During “Episode 6: Mall Meltdown,” players will encounter a wooden fence with the graffiti “FOOT” sprayed on it. Destroy the brick wall on the right to enter the next area and break the nearby pink trash bin for the fourth Diary.

Irma’s Fifth Secret Diary Location

  • The fifth Diary is in a toolbox on a roof in “Episode 7: Roof Running Reptiles.” Ninja Turtle fans will know they’re on the right rooftop when they spot a neon pink sign nearby.
