Butterflies and Squirrels

Squirrels are just bushy-tailed rats. Butterflies are just colorful moths. Squirrels and butterflies are "cute" or aesthetically appealing to many more people than rats and moths. The cute creatures are almost identical to the ugly ones except for their one redeeming feature that seems to overshadow all the rest of the negative associations we have with these animals. I bet there are plenty of other things that fall into this category of having one redeeming quality. Feel free to post a comment with your idea for an element of this set.
