Gazzer are charcoal-black slugs that are similar to Armashelt and Crystalyd Slugs and have orange armor with pale-yellow lining and sand-blue antennae. The only members of the Shane Gang to own a Gazzer is Eli Shane and Kord Zane. In "The Journey Home" It was first seen making Lode laugh so much that he fired one of his Ghouls at Locke by Kord Zane.

The Gazzer is a pure strategic slug. Hilariteaser can make the opponent laugh uncontrollably and can make them misfire, firing a slug at their ally or in the wrong direction. Stompchomp "disables" an opponent, making them focus on dancing instead of slinging, and allows a slinger to fire a Rammstone, Tazerling or Hop Rock to finish an opponent off. Taggro is good when making distant shots, and ensures the slug will not miss the enemy. It also helps the slinger to make precise shots.
