Who's There? in Bloomington, MN

Brothers Drake, Dreyfus, and Dale are very different dragons who scare the villagers and make veggie stew. But one day, they're startled by a curious sound.
What could it be?
The first in a delightful series, "The Brotherhood of Dragons," here begins their story:
Hear ye, hear ye, of tales untold
Ears and eyes of all behold
Drake, Dreyfus, and Dale
Fearless dragons eons old
