What the!?

I'm out enjoying the moring sun like most mornings on my tie-out. Then low and behold I spy something new invading my territory. Mom's inside making a pot of coffee and she finally hears me yelling for her. This thing is just outside my reach so I try talking to it to see if it might come to me if I'm nice. Nope, doesn't work. Mom comes out to see what all the commotion is about. And says that it's something called a crawfish. Neither of us can understand why it's in the middle of our backyard. The creek is a good 150 yards away. It doesn't seem to be hurt. Mom being the kill-joy that she is picked it up and put it in Titus's outside waterbowl. That big stooge tried to give it kisses. Any guesses how it got here or what we should do with it?
