Pete the cat loves the buttons on his shirt so much that he makes up a song about them, and even as the buttons pop off, one by one, he still finds a reason to sing.

"Yellow Bird has found a button and wants to share it with Red Bird and Blue Bird. This is just an ordinary button. It does not do anything when you press it. But when Red Bird and Blue Bird give it try, they are delighted to find that the button does not do nothing, and that is something!"--
