The Price of an Egg
First part of the quest (Retrieve a Package) is rather bland. Some story, with an orange named adversary boss at the end, would have helped add a bit colar.
Once past the two dozen carrion crawlers and slime, one then encounters what should be described as a "monotonous" run of 30 or so Purple Worm larvas ... left-right, left-right, left-right. Some variety would have been nice. Being able to move through earth, why do they insist on coming up from below? Why not from above or from the sides. And some other monsters (Underdark Beetles) underfoot might broken the monotony. Just a little constructive criticism here.
For the end battle in the "nursury", it felt as if the little tykes didn't contribute much to the challenge.
