There is a Sooper Secret to be found. When you first get the intermission sequence, you see you are entirely surrounded. Near the left in the far distance should be a pool table. Go over to it. Once there, notice the pool balls on the table. Use your character to push the balls into the nearby fireplace. Once you get one in, you should hear the same sound that plays when you get a rainbow monkey. Keep track of all the pool balls. If you lose one and cannot find it, you cannot get the Sooper Secret. When you get all the pool balls in the fireplace, a strange icon drops from it. Run into it and you should get a Sooper Secret unlocked message.
