The Afton and The Orphan (FNAF and Undertale crossover)

This is a sequel of my BATIM and FNAF crossover book, Nostalgias Collide, if you haven't read it yet, read it first. It's been weeks since the Afton kids had met Bendy and freed them from their studio prison. However, there is another kingdom that need to be saved. Chris Afton, the youngest of the kids, will be the first to do the job. After Micheal told him the story about a monster kingdom underground that he remembered their mom told him at Chris' age, Chris ends up falling down the same hole that Micheal told him to beware. Freaked out, Micheal sends their group of friends to get him but Chris meets another boy down there who seem to fall before him and they work together to either fight monsters or spare them all.

Disclaimer, FNAF belongs to Scott Cawthon and Undertale belongs to Toby Foxx. I don't own them or most of the pictures that appear in this story but the picture of the kids in the title I drew myself. This story will be told like the entire Undertale game but I will add some original parts.
