As heartfelt as Frozen's climax was, the movie musical could have benefited from a brief reprise of the song "Do You Want to Build a Snowman?" at a key moment. So one fan wrote the lyrics to a reprise and another gave it voice. Spoilers below.
Over at Musical Catbug, phananigans wrote a reprise of the song, which he suggests should be sung by Elsa after Anna becomes entirely frozen:
"Yes I wanna build a snowman…
I'm sorry that it took so long… I didn't know I needed you…I really do… and now you're gone… please…just ask me once more… just one more time…I promise I'll open the door …yes I wanna build a snowman…"
And Scarlet-Glow recorded the song:
Nice job, folks. A perfect addition to the film.
