This horrible ball of slime is what sprang out at me:
It was the exact size of a chicken egg, covered in 1/2 inch thick layer of slime, and smelled terrible. I thought I had dug up an alien baby. I was not happy that my serene garden contained such horrors. I knew Dani wouldn't believe me if I simply described it to her, so I scooped it up on my trowel and carried it into the house. She was taking a nap, but this was too important for sleep! Her reaction was: what the crap is that? Is it alive? How about you put that outside?
I plopped it onto the front porch and, in the interest of science, I cut it open. That little bastard was as hard as a rock. It also released a hideous stench once it was sliced into. It took being putrid very seriously.
I have no idea what the crap this thing is, which means I need to hit the internet. I'm guessing if it truly is not an alien baby that is about to sprout tentacles at me, then it is probably a fungus of some kind. I get on Google images and type in the most unfortunate series of words, bringing up pictures I should have never seen, wish I could erase from my brain, and will probably alter my psyche forever. Things like mucus, eggs, slime, gross, fungus, etc. It was a bad idea.
Finally, I discover that my unholy friend is a stinkhorn "egg" or fruiting body. How interesting is that? It's deliberately nasty to attract flies, and the adult stinkhorn looks disturbingly like a phallus with some kind of terrifying STD.
Of course I had to show the girls. They were delighted and yelled, "GROOOOOSS!" and poked it with sticks. Then I put it in a bowl on the porch and forgot about it until today. I went to dump it out and saw that it has grown. AHHH! It's still alive! It's trying to reach for me! And it's slimier! I don't like nature anymore!
