Sebastian leads Ariel, Triton and an Atlantican chorus into a charming Atlantified version of "Deck the Halls. This song was originally released as part of the mini-album "Ariel's Christmas Under the Sea".
I penned these lyrics by ear, so feel free to let me know about corrections in the comments.
Sebastian:
All right, is everybody ready? Ariel? Flounder? Your Majesty? Yes. All right now, here we go.
Deck the halls with shells and the seaweed
Fa-la-la-la-la la-la-la-la-la
Lots of sea stars, that is what we need
Fa-la-la-la-la la-la-la-la-la
Wear your shiny pearls and the coral
Fa-la-la la-la-la la-la-la-la
Come on now, while we sing this Christmas a-carol
Fa-la-la-la-la la-la-la-la-la
See the shining tree that's before us
Fa-la-la-la-la la-la-la-la-la
Aww man, strike up the harp and join in the chorus
Fa-la-la-la-la la-la-la-la-la
Swim with us in merry measure
Fa-la-la la-la-la la-la-la-la
While we sing of Christmas a-treasure
Fa-la-la la-la-la la-la-la-la
Fast away, the old year, it passes
Fa-la-la-la-la la-la-la-la-la
Hail the new year, you lads and lasses
Fa-la-la-la-la la-la-la-la-la
Now the fish is sing all together
Fa-la-la la-la-la la-la-la-la
Forget about the sea and the weather
Fa-la-la la-la-la la-la-la-la
Deck the halls with shells and the seaweed
Fa-la-la-la-la la-la-la-la-la
Lots of sea stars, that is what we need
Fa-la-la-la-la la-la-la-la-la
Come on everybody, wear your shiny pearls and the coral
Fa-la-la la-la-la la-la-la-la
Aww man, while we sing this Christmas a-carol
Fa-la-la-la-la la-la-la-la-la
Fa-la-la-la-la la-la-la-la-la!
Aww that was beautiful! You, too, Your Majesty.
