Even in a nightmare, the monster Grimace could not have imagined that his favorite milkshake could become an enemy and pose a danger to the monster's life. However, this happened in Grimace Invasion. When there were too many monsters, the cocktail rebelled and armed itself. He only wants to fall into the hands of good buyers: boys and girls, their dads and moms, grandparents, and not some purple monsters. We'll have to show them who's boss at McDonald's. As a control at the bottom, you will find two arrows: left and right, by clicking on them, you will make the glass of drink move to the right or left, respectively. He will fire automatically to spray fire on the Grimaces that appear from one side to the other in Grimace Invasion.
