Grocks

Grocks (Japanese: 岩石生命体, Ganseki Seimei-Tai - Rock Life Form) are a race of monsters, as they name suggests, are made of rock, and are the main antagonists and enemies of the Dillon series that come in many shapes and sizes, though most resemble boulders with stubby legs, which oddly enough resemble human feet. These creatures began terrorizing the West, but no one knows why. They attack en masse at the blast of a foghorn. A rare few have arms (Gungrocks and Diggrocks) or lack legs altogether (Springgrocks and Ultimogrock). They are characterized by their appearence when the sky turns red, preference to attack in waves of three, and their love of Scrogs, the various villages' livestock. There are a total of 40 species of Grock in the Dillon series, three of which are barrels (which are not true grocks but have the defense of them). Grocks have "bones" but they are just stones. If you collect 5-stars in every stage then you can view a gallery of all the Grocks that appear in the game from Sal's Grock Collection.

Types of Grocks

• Regular Grocks (Footgrocks, Weakgrocks, etc.)
• Special Grocks (Ramgrocks, Gungrocks, etc.)
• Neutral Grocks (Snaggrocks, Veggrocks, etc.)

Trivia

• Some grocks resemble Goombas from the Mario series.
• The main motif of the darkened sky and the red coloration during the Grocks' attacks should be due to volcanic activity, as the high concentration of sulfur dioxide expelled from the craters of volcanoes (and Grock Dens) often left the sun setting with a very reddish color
