Its a holiday on the second Sunday of June. Its when men decorate there Grunskins with paint and glitter in honor of that body part. In tradition a man is suppose to have a woman lick it 14 times before painting.
Faces made of a single pile of sand. Pebbles, shells, sticks and seaweed are used to define facial features such as nose, eyes, mouth, ears, etc. Grunkies are meant to be a little grotesque. They are said to keep watch over swimmers and protect them from dangers, such as the undertoad.
