For example, the preponderance of bears on children's clothing. They're cute and all, but don't bears, like, maul people?
I guess you can make anything cute by giving it a big head in relation to its body (and yes, it looks like I'm right, having done a google image search for "Cute Cthulhu" . But I still wonder why bears got the cute treatment, and not, say, Vultures. ("Cute Vulture" doesn't do nearly as well in the image search)
Maybe it's the "Teddy Bear" thing, but I'm not sure whether that's a cause or an effect.
