Spiders. Nightmares on eight scuttling legs. An entire group of creatures so bizarre, menacing, and creepy in their habits that a specific phobia has been dedicated to them. It's proven to be surprisingly popular. Or unpopular, as the case may be.
For Fluttershy, though, there's a lot more to them than that. A friend to all living creatures can hardly discriminate amongst her charges. And surprisingly for her, a day when she devotes her time and energy solely to these alien animals proves to be one of the most enjoyable ones of her week.
