If a high enough proportion of meat is consumed during the stage, this allows the player to access further carnivore mouths (reptile, insect, fish, etc.) in the Creature Stage, of which one, the Gobsterclaw, resembles the Jaw with the teeth removed. In the Creature Stage, the Jaw has a Bite and Sing power of 1.
- Through Modifications, various hidden part handles can be accessed. These handles allow you to change the width, shape, and length of the Jaw. Through the Hidden Cell Editor or Modifications, 3 other variants of the Jaw can be accessed.
- When in Cell Stage, you can use this piece to pop bubbles as well as attack and eat meat chunks.
- Contrary to some belief, this mouth is not required in order to access the other carnivorous mouths in the Creature Editor: all that is required is for your cell to end the stage with a carnivore card, which can be done with a Proboscis if a high enough ratio of meat to plant matter has been consumed.
