It makes for a good alternative to "old faithful": the slaying of rats taking up residence in an unfortunate commoner's cellar. Assuming you don't want to simply resort to using rodents writ large (e.g., Giant Rats or even Osquips), you can substitute Spiders for Rats if the danger level needs to be kicked up a notch. Here's another idea for a low level animal-based quest that I have been toying with as of late ->
In Deepingdale, Elves or Half-Elves who are "coming of age" occasionally prove themselves by seeking the elusive Deepingdale Owl*; because this particular bird is rare, the act of harming one is frowned upon more so than usual. Therefore, these spirited youths prove their resourcefulness by bringing back a less destructive sign of their success...such as a feather, a lone/abandoned egg which was imperiled or even a live specimen (which must be well treated).
*A beast which I have yet to fully describe, but which likely features outward characteristics evocative of the sylvan folk, is vaguely magical and/or possesses a greater-than-usual longevity (like an Elven Cat or a Cath Shee).
