The Final Unggoy, also referred to as the Jerk Store Grunt or Seinfeld Grunt, is a talking Grunt in Halo 3.

Description
This Grunt is found cowering on the edge of a cliff right before the player goes down the ramp to leap into the Forward Unto Dawn's hangar in the level Halo in Halo 3. As the player reach a white rock arch, turn the vehicle slowly to the right and a narrow pathway will be visible. At the end of the pathway is the Grunt. If the player approaches him, he will say:

However, discovering the Final Unggoy may leave the player unable to complete the end of the level as the platforms would have broken apart, thus rendering no possible route available to reach the Forward Unto Dawn.
