An unexpected visitor

We arrived home late tonight after running some errands and while I was out in the front yard trying to get Lola to come back after she had been chasing the neighborhood rabbits, Austin decided to go out back and turn off the pool filter. Of course we didn't leave any lights on so it was completely dark when he went back there. All the sudden something by the pool jumped towards him and scared him. Apparently Kermit was taking a swim in our pool. This is the second time we have had a bullfrog in the pool this summer. I always name all the animals that wander into our yard.. 2 weeks ago we found Minnie Mouse swimming in the pool... at least frogs know how to swim. We set Minnie free, but I think we are going to let Kermit hang out for a while.
