The Great Water (S02E04)

Upon reaching the Big Water, the rabbits find themselves cut off from Kehaar. They marvel at their new environment, especially the salty ocean. However, they quickly notice that the tide is advancing toward them. Meanwhile, Kehaar reunites with his old companion, Katerina, only to discover that her demeanor has changed and she isn't as welcoming as he remembered. Just as the rabbits are about to be swept away by the rising sea, they receive assistance from the Puffins.
