So, I remember reading a book my grandmother had when I was little. It was about these creatures that were basically a small ball of fuzz, but they spread happiness and joy wherever they went. It was illustraded like it was a kids book, but years later when I read it, there was a definite underlying message. It was all done in bright colors.
Anyway, this one family finds a pair of the fluffy things, and then they have more fluffy things, and everyone loves their fluffy things, and then EVERYONE in their happy town gets one for a pet. However, pretty soon, there are too many of the fluffy things to support, and everyone gets jealous (or something, I’m really struggling to remember it all here) And all the fluffy’s die or leave, or maybe the town people leave? Anyway, does anyone have any idea of what book this might be?
