Dammit... YohakuAki beat me at my own game: some days ago I was writing a story about tossing a full grown yukkuri into a washing machine, but it seems that he was faster than me. Also, he used a koyukkuri.
Also, for the 'question of the day' challenge: "Why is Reimu in a hurry to die?" The winner will receive an original Yukkuri-Drum Set and the metal sticks to play it!
