Scared awake - what is that THING in my grapefruit

I'm not what you would call a morning person. I'm not a groggy person, I just like to acclimatize myself to being awake (which reads: don't yammer at me unless you want me to give you the glare of death). But I pretty much went from 0 to 60 when I opened my grapefruit and found this:

At first it looked like some kind of creature just under the surface of the fruit. And in these gory red grapefruit bits...tell me it doesn't look like some weird fetus.

Once I got my heart rate to slow down I realized what it was and took these hurried, horrible photos. I threw it in my mulch pile. Maybe I'll get a grapefruit tree out of the deal. ;)
