The Gruff Goat is an enemy found in EarthBound. These big, brown, and white-bearded goats are located in Winters, Eagleland and is first encountered by Jeff and the Bubble Monkey. They also make an appearance in Dungeon Man where they aren't fought but, are one of his "pets". They have a terribly high offense and defense, but quite low HP.

Their "Ram and Trample" attack can deal moderate to high damage. The most feared attack is the "Tear into the Target", dealing very high to major damage. It is recommended the Jeff is having a constant supply of Bread Rolls and Cookies, to avoid instant death. After this enemy is defeated, it awards Jeff and co. with 20 EXP, drops $9, as well as a salt packet (16/128) a time.

Their in-battle theme is, "Battle Against a Weird Opponent."
