This story starts off with Tails, the cheerful gold fox we all know. He creates a vortex leading to other universes. Not having the slightest confident to go alone, he calls up his buddy Sonic. They set it to travel to "The Mushroom Kingdom" but the machine has a slight malfunction. Now they end up in another universe, something we all know as "Undertale". || W.I.P!

It's been three years since the doctors had diagnosed you with an incurable disease, which they had not named since you are the first patient that had ever had it. Randomly, your body would start hurting all over, your eyes felt like they would be on fire, and your limbs felt like they were being torn off. You have endured the pain for a long time, and felt like it's almost the end.

"Don't mistake my kindness as my weakness. I'm being kind to you 'cause I'm repaying you for your kindness. But if you it with something that isn't good at all. I'll make sure that MY kindness will be the last thing you'll get. " I heard that a couple of times from dad. Believe me I was born into the throne. I was born to be a mafia leader. Daddy was the boss everybody follows him. He taught me how to use weaponry from knives to a gun. He taught me well. Bang. "He's dead. Find her then kill her. Make sure she's dead too." "But boss, she's your cousin." Another one "I don't care, all I want is her dead. Find her and bring her to me... I'll kill her myself." ~~~~~~~¤~~~~~~~~~~~¤~~~~~~~ This is my first book so please don't throw knives at me or hunt me then shoot me. Don't have high expectations that this book would be like wowzers. I do like some of your help I'll listen to your ideas that would help this story. I'm already apologizing for wrong grammar and if I update slow.

The second part of the fanfic of Flowerfell: Overgrowth. I did not make the first part, and the second part has as of now not been viewed by the creator of the AU of Undertale or by the writer of Overgrowth, part 1. This is an unofficial part 2, and I believe there is an official one. You can read the first part here, and I HIGHLY suggest you do, as you will not understand most of the story without it. Here is the link (Hope it works, Im not one to usually use Wattpad): http://archiveofourown.org/works/5734642 If it doesnt work, just copy and paste it into your URL Bar at the top left, and if even that dont work, search for 'Overgrowth Undertale fanfic Flowerfell AU' in Google and you will find it eventually. Overgrowth, part 1 has been written by SociopathicArchangel on Archive of our Own and he/she (sorry) has given me permission to write a second part. This Story contains similair content to Overgrowth, and thus it has some scenes of violence and is something your supposed to be sad about, but Im not sure that will work since this is my first ever close-to-finished story. Hope you enjoy, and have a nice day regardless! :D

Based on the Underfell fanfiction "Overgrowth." Please read it before you read this. All of the underground knows of the song. It's sung at funerals and as lullabies. It's a haunting melody that often rings throughout the minds of monsters. But even after they gain their freedom to live in the new world of hope, it's tune has never left Sans. In memory of my precious nephew and great uncle. Rest in peace.
