Mr. Toad lives in the backyard, we have watched him grow over the last couple seasons. He and Argus are strange friends. At first I was concerned Argus would just eat him, but over time he is more curious than hungry. He looks for him when we go out, and if he is there like he was tonight, he will sit and stare a few feet away. Mr. Toad thinking he is invisible will stare back, and that is it, that is the base of the relationship. Staring. Then we go out again and he has moved on, and Argus will sniff everywhere to find him.
