"Stella Ella Ola" (Stella Stella Ola), also known as "Quack Dilly Oso", is a clapping game where players stand or sit in a circle placing one hand over their neighbour's closer hand and sing the song. On every beat, a person claps their higher hand onto the touching person's palm. The cycle continues until the song ends at which point if the person's hand is slapped, they are considered "out" and must stand or sit in the center of the circle, or leave the circle and watch from the edges.
If the player to be slapped pulls their hand away fast enough, the person who attempted to slap the hand is out.
