For the longest time, Billiam was known to be an ordinary, average moose. A very large moose, in fact, but about as normal as a moose can get. All this changed when he became the best teacher in Stillville. No longer is he ordinary—he is extraordinary!
One day, Della, his moose-mate, tells him her pond is messy. Messy, not mossy. Billiam checks it out, and Della's pond is indeed messy, filled with bad chemicals and old containers. True to his extraordinary self, Billiam plans and plans until he figures out how to solve the problem to keep humans from dumping chemicals into his lovely mate's pond.
