The world of Underfell was a dark and twisted place, where the once-kind-hearted monsters of the Underground had become cruel and vicious. In this harsh world, Frisk found themselves falling into the Underground once again, but something was different this time.
As they landed on the ground, they looked around and saw that everything had changed. The once vibrant and colorful world was now replaced with shades of red and black, and the monsters they encountered were no longer friendly.
Frisk soon realized that they had landed in a different version of the Underground - one where the monsters had fallen to their worst tendencies and the rules of the world were completely different.
As they made their way through the dangerous territory, Frisk encountered a group of monsters led by a menacing figure known as Underfell Sans. He warned Frisk that they were in his territory now and that they should turn back before it was too late.
But Frisk refused to give up. They were determined to find a way out of this twisted world and return to their own. With the help of a few kind-hearted monsters they encountered along the way, Frisk set out to navigate the treacherous paths of Underfell and find a way back home.
