Overview:It's the annual Net-A-Fish-And-Toss-It-Back-A-Thon over at the pond! But something's not right - Nature Cat and his pals have netted exactly...no fish. Last year there were so many fish they couldn't net 'em fast enough. Where did all the fish go? The answer comes from an unlikely source - Flo the Heron, who lives at the pond and hasn't had a good fish dinner in days. Nature Cat will do whatever it takes to find some fish for Flo. Onward and fishward!
