Halo 5 Singing Grunt Easter Egg

The Singing Grunt is a lone Grunt sitting on a ledge and singing to himself in the Halo 5: Guardians level Reunion.[1] The Grunt holds the Grunt Birthday Party skull and will drop it once killed.

The Singing Grunt will sing for roughly 20 seconds and then stop. He will not acknowledge the player and can be killed easily.
