ACK! I had one of these in my mouth!
I was spearfishing off the Kona Coast of Hawaii and had caught a Needlefish which I was cooking for lunch. As I was sucking the cheeks and eyes out of the fish, I noticed something weird making it's way out of the fish's mouth. I spit it out of my mouth and it was this ugly Fuck. Scary. Didn't know what it was till now. Thanks for the awesome animation. Glad I caught the thing before I had an anus attached to the vein in my mouth where my tongue used to be.
AAAAAHHHHHHH!!!!!!
