Stone-Eye

Stone-Eyes are giant grey stone heads that appear in New Super Mario Bros. U and New Super Luigi U. They mostly inhabit desert-themed levels, and either move in numerous different patterns (e.g. swaying, up and down, to the left or right, etc.) or are completely stationary. Based on their movement patterns, they can assist and/or hinder players.

Some Stone-Eyes can be moved by Ground Pounding on top of them; this is often necessary to reach things such as Star Coins or paths to secret exits.

Mario Party 10
Stone-Eyes make a cameo in Mario Party 10 in the minigame, Fruit Scoot Scurry.

Trivia

 * Stone-Eyes will have their eyes fixed on the player, but if the player performs a Spin Jump, their eyes will spin.
