The Eyeball Berry: "I'm watching you, always watching..."

In my survey of the yard following the storm, I also came across this thing staring up at me:

Now, this is one of those things in Nature that just makes you scratch your head. You KNOW it's not really a disembodied eyeball, yet you almost want it to be, simply to creep out your friends!

I mean, look at how perfect this thing is: it's got "veins" and everything!

Well, (unfortunately) this is only a weird-looking berry that happens to resemble an eyeball. But still, naturally occurring prank material is rare, and I wish I could use this somehow...
