Bonker

Bonker is one of Stagar's upgrades in the Slush Invaders: Game that allows his spin attack to hit multiple enemies.

With this upgrade, enemies around Stagar will also get caught in his combo, causing an Area of Effect. It costs 20,000 points.

Trivia

 * If the Hammer upgrade is unlocked, combined with this upgrade's AOE, it is possible for Stagar to stun multiple enemies at the same time.
