A musical instrument made from the cardboard tube of a paper towel roll. The player places the tube to their mouth and says "roo roo" repetedly. Can also be made from the center of wrapping paper rolls.
Whenever I come to the end of a roll of paper towels, the kids yell "I GET THE ROO ROO", and they drive me nuts.
