This is a song-game played by Puerto Rican children in school yards for centuries.
Children hold hands and skip in a circle while singing the song over and over.
The children holding hands try to prevent the cat from sneaking inside the circle and touching the mouse. Once the cat comes into the circle, the mouse, aided by the dancing children escapes outside. The cat then tries to sneak out of the circle to catch the mouse and so on. The cat is allowed to force his way in as long as he doesn t hit or hurt anyone. Children scream instructions and warnings to the mouse.
