Softy, Fuzzy Blob Turns Into Stuff Of Your Nightmares

Hey, what's that soft, fuzzy thing sitting over there? Kind of looks like a giant caterpillar. Looks soft and fuzzy. Hey, maybe I'll touch it! Yeah, that seems like a good idea! Here I go, and ... and ... OH MY GOD! WHAT HAVE I DONE! RUN AWAY, RUN AWAY!

(This is actually a mating ball of harvestman spiders, a k a daddy longlegs. They look mighty creepy, but they are completely harmless. Still, they were probably mad they got interrupted when they were trying to get it on.)
