Okay, so... This is obviously based off on that very moment when Frisk fell down Mt. Ebott and woke up on that flower bed.
Credits to Toby Fox for the OST and story and whoever drew this beautiful backdrop.
Come on up the mountain, my dear
Come on up and see what’s inside, my dear
Ah, my dear, won’t you take a quick peek?
At the top of Mount Ebott, at its very peak?
Ah, my dear, please don’t fall!
Always remember to have a firm grip!
Oh dear! Oh dear! The child has lost their grip!
Deeper and deeper they went into the dark hole
All of those rumors
All of those lies
Caused the poor child
To venture out into the wild
Oh, what’s this? Oh, what luck!
The child is indeed still alive!
But I do never cease to think,
About how this bed of yellow flowers kept them alive
