Yatta Yatta Yatta Sooper Secret: While playing as Numbuh 5, get to the part of the stage with the disco ball. After the first intermission sequence you are surrounded, and in the far distance to the left is a pool table. Push every pool ball into the nearby fireplace; you will hear the rainbow monkey sound for each one. Lose a ball and the secret is gone. When they are all in, an icon drops from the fireplace: run into it to unlock the Sooper Secret.
