Singtoo is a Maxis-made creature, present in the final game.
It possesses Terrorpin mouth, Coygamine eyes, Elfinmagick senses, Doubelbow arms, Stompbottom legs, Ultrarolfer graspers, Threepaw feet, and Nurple details.
- It is similar subspecies to the creatures Singwon and Singtwee. Unlike the other two, it has the "Terrorpin" mouth instead of the "D'orca" mouth. Like the others it has a row of "Nurple" details on its back.
- The "too" ending may be a simplification of the number two or can mean that it is descended from Singwon or Singtwee.
