Wil changed his name to Wild Horse, which fully represents his old name, but projects more of his real character. Here is a picture from earlier today, when he had a friendly lizard climb onto his hat.
Here is a bit of a detail of the lizard on his hat
Wild Horse had saved the lizard from a cat which was trying to kill it. And the lizard felt safe on the hat and actually crawled back onto it once when he put the hat on the ground and took the lizard off gently.
Ultimately, the lizard went off into the grass, and Wild Horse picket seeds with Mac and i late into the night, with only fond memories of his new friend.
