Mutagen Tracker
The Mutagen Tracker, also called the Ooze Scanner, is a device created by Krang and used by Shredder for the purpose of locating Muckman in the 1987 TV series episode Muckman Messes Up. In the 2012 TV series it was created by Donatello, for the purpose of locating Mutagen (as the name implies). It first appears in The Mutation Situation.


  • The noise made when Donatello turns on the device is the startup sound of the classic 1989 Game Boy (which the Mutagen Tracker largely resembles).
