Almost every episode of TMNT: Shredder's Revenge has secrets and collectibles to uncover. These are not required to complete the game's story and see the end credits, but collecting them will give players a chance to unlock some achievements and trophies.
This guide will show TMNT: Shredder's Revenge players where to find all five secrets in Episode 6, Mall Meltdown.
TMNT: Shredder's Revenge Episode 6 Secrets
Secret 1 - Secret Diary
After destroying a brick wall to enter a food court-like area, players will see a breakable trash can/tray holder to the left of a taco shop. Destroy it to find one of the secret diaries.
Secret 2 - VHS Tape
After going up the escalator to the next floor, players will eventually pass by a clothing store with some clothing racks in front of it. Keep going to the right to spot another one of those trash cans/tray holders sitting between two potted plants. Break it to find a collectible VHS tape.
Secret 3 - Napoleon
In the same area where the VHS tape is, players will see a cutout board of the Punk Frogs from the old-school TMNT animated series. Break the display to find a frog named Napoleon.
Secret 4 - Vernon
After going up to the next floor, head to the arcade to find a popcorn maker machine. Break it to find a guy named Vernon. He's a cameraman that was introduced in the animated TMNT '80s series.
Secret 5 - Disgusting Bug
After getting through the arcade, players will find another popcorn machine. Go ahead and break it to find the last collectible of Episode 6, a disgusting bug (what was that doing in there?)
Now that players have collected all the items, they'll need to finish the level by defeating Tempestra in a typical TMNT boss battle.
TMNT: Shredder's Revenge automatically saves game progress when collectibles are picked up, so if players die at the end of the stage, there's no need to gather the items all over again.
After players complete all 16 Episodes, they'll finally get to play as Casey Jones, the only playable character that needs to be unlocked.
TMNT: Shredder's Revenge is available for Linux, PC, PS4, Switch, and Xbox One.
