Pony Twinkleheels in "The Race"

When Johnnie Green turned Twinkleheels and the old horse Ebenezer into the pasture, the first thing they did was to drop down on the grass and enjoy a good roll.

There was a vast difference in their actions. Twinkleheels was as spry as a squirrel. He rolled from one side to the other and back again, jumped up and shook himself like old dog Spot, almost before Ebenezer had picked out a nice, smooth place to roll on.
