Pony Twinkleheels in "A Big Little Pony"

But Twinkleheels and Miss Kitty were not alike in any other way; for Twinkleheels was both merry and good-natured. He let Johnnie Green pick up his feet, one at a time, and clean them. And the worst he ever did was to give Johnnie a playful nip, just as Johnnie himself might have pinched the boy that sat in front of him at school. Only, of course, Johnnie Green wouldn't have used his teeth to do that.
