It's the night before Christmas, deep under the sea. Seashells are hung on coral with love while vision of periwinkles swim through mermaids' heads. A lobster is about to doze off too when old Saint Nick appears in a huge conch shell sleigh pulled by eight lively sea horses! The jolly walrus bestows his gifts and soars out of sight with a timeless message about happiness and love. Clement C. Moore's classic poem, reimagined in a magical underwater setting, is a rollicking way to welcome Christmas.
