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.

The squodgiest, snuggliest, most frobbulent blongalubjubulent creature in existence. Cuter than the cutest rabbit, and then some. The cutest action achievable by the roo-roo is the hibernation in a cocoon of bedsheets, and the ensuing struggle to escape.
The roo-roo is with the pink rabbit of happiness!
