Alien Life Form

A few days ago I went outside to the back, and I saw this thing. It sure looked weird, and I didn't want to touch it, not being sure what it was. I finally picked it up with a shovel and put it in a jar - it's about the size of a fist - and took it to one of my colleagues. He's not sure what it is either. It looks like either a slime fungus or a deflated kid's toy. He's never seen a slime fungus this big though. I just think it's an alien that ended up in the back yard.
