<human>: Can you condense the text into three sentences or less?

It was a while now since I played through all the Half-Life 2 episodes and I'm feeling an itch to get back and do it again. There's just one little hitch; I'm slightly arachnophobic... This makes playing through places like Ravenholm almost impossible. The first time I played through the series I had help from a less skittish friend who alternated playing the game and exclusively got to play through those areas.

I've been googling this for a couple of days but still found nothing. I've bee searching for ways to at least replace the texture of the headcrabs (especially the poisonous ones *shudder*) with something less intimidating. I found this video and I've franticly searched for the textures for them but haven't found any: 

Something like that would really help me get through the game on my own, despite my somewhat "pansy" phobia.
If anyone can help me with a way to do this you'll be my hero for life! (half-life?) :)
<bot>: Is there any way to replace the Headcrabs textures to something less frightening/"spidery" in the HL2 Episodes?
