Which classic Skull creates confetti after headshots on grunts?

The Grunt Birthday Party Skull creates confetti after headshots on Grunts.

When this Skull is active, a headshot that kills a Grunt triggers a burst of colorful confetti and a celebratory sound effect. The joke turns an otherwise routine enemy defeat into one of Halo’s most recognizable pieces of comic visual feedback.

Grunt Birthday Party is part of Halo’s broader Skull tradition: optional gameplay modifiers that alter combat, presentation, or difficulty. Skulls reward exploration and experimentation because they are commonly hidden in unusual locations or unlocked through specific challenges. Depending on the Halo release, the exact activation method and Skull menu can differ, but the confetti effect is the defining feature of this one.

The effect applies specifically to Grunts, the small Unggoy infantry species of the Covenant. It should not be confused with Skulls such as Fog, which removes the motion tracker, Mythic, which strengthens enemies, or Cowbell, which changes explosive physics. Those names refer to different modifiers. Grunt Birthday Party is also an example of Halo’s habit of mixing serious science-fiction warfare with playful secrets and Easter eggs.
