Can you imagine what it'd be like if you came home from work after a long day of paralyzing spiders to pack zombified into your babies lunch boxes*... only to find the door to the lovely little house you built from scratch blocked by THIS FACE.
This face. (see photo) and it's some guy who won't leave your house and he's using his head to block the entrance. You try to pull him out, but he's locked in with spines!
And do you know what he's up to?
He's guarding your house hoping it will get him LAID. I kid you not. He's got a girlfriend with a similar FACE and she is coming over and if she is impressed with YOUR house they will lay eggs on your eggs and it's all over for your little babies.
You get so disgusted you buzz off to start over.
