A visitor in the garden

I was in the yard the other day and looked down on the soil to see something moving. At first I thought it was just an earthworm, but then I noticed little arms and feet as it crawled along the ground.

I think I've got a Newt here. What do you think?

I've never seen one in the garden here and frankly, I haven't seen it since. I did find it after it had rained for several days, so maybe the wet conditions attracted him to my yard. Or maybe he just wanted to play on the kids' playground by himself!
