In the lakeside town of Echo Bay, something unusual has happened—everyone is gloomy! The frogs won't tell jokes, the beavers don't splash, and even the sun seems to hide. But one cheerful duck named Paddles refuses to give up on smiles.

With kindness in her heart, she sets out to deliver tiny surprises—flowers, pebbles, poems, and laughter—to her friends all around the lake. One by one, the animals rediscover their joy, and soon Echo Bay shines again.
