Fletcher would much rather nap than dance, but he's still upset when someone tries to ruin the masked ball celebrating the opening of a new park. Could it be the annoying squirrel who doesn't want to share his wooded home with a bunch of humans and, even worse, dogs? Or maybe the young park ranger who's always getting mysterious calls on her cell phone?

Fletcher is sure she's innocent. After all, how could anyone who likes salami (and is willing to share it with a certain basset hound) be a villain? But can his unerring nose unmask the real culprit before the dance turns into a disaster?
