The impossibly naïve Sniffles gets volunteered by his buddies to bell a troublesome cat. Sniffles does his best to get the bell on the nasty housecat. After several tries and narrow escapes, Sniffles accidentally bells the cat. Back with the other mice, he is now a hero. Sniffles tells them (while he crosses his fingers) that he demanded that "Mr. Cat" put the bell on.
