Joy of Tradition (an Octonauts Holiday One-shot)

Commander Stella's Saga (AU-ish).

~Stella, Barnacles, and Tacker are visiting Bianca and the cubs for Christmas, the first since Barnacles and Bianca entered adulthood. But there's immediately a problem; both bears are distant, feeling their lives have drifted apart during the years they were separated, living their dreams after the carefree joys of their childhoods, especially at the holidays. It's up to Stella, Tracker, and the twins Ursa and Orson to help the elder bears rediscover that joy~
