## Description

The Gremlin is Back. And It’s Feeling Wicked. When we launched the original Gremlin, it wasn't just a ball—it was a problem for the pins. But even the best mischief-makers need a darker side. Introducing the Wicked Gremlin, the next evolution in high-performance lane destruction. We kept the heart of the original alive, but we’ve wrapped it in something far more sinister.
