Undertale reminds me so much of bad end night it's not even funny
but this is gonna be divided by characters, and when nobody specific is singing it'll appear as 1. When it says all, it means everyone except Frisk/Chara.
1: in the deep mountains
a small child has been lost
she looks around and starts to wander off
Not looking at the path layed ahead
She fell down a hole, almost bringing her demise.
1: They wake up, surrounded by flowers
They'll never guess what a night they're in for
A large door starts to creak open
Toriel: Oh my, child, what a great fall you've had...
Papyrus: Oh, please come in!
Sans: We'll cater to yo
