You left the snail farm and out the way of Napstablook.. Sheesh that was hard.. At least you still alive right? You sigh softly as Flowey wrapped itself tightly around your arm as you looked at Flowey "what is it Flowey?" Flowey was a bit scared "[Y/N] I know you want to get out.. But you need to know.. You have to fight back.. Your gonna die.. In this world its kill or be killed" You sigh softly as you looked up head "yea i know Flowey.. But still others deserve the chance to live and be free.. And i gonna show them they can change.." You looked more but then tripped and stumble some road and into some water where you heard something. You got up but your shirt and pants was wet.. Fuck you look around to see where you heard something but found dump.. And from their you quickly panicked noticing you fell on trash water.. You then heard something and look ahead of you.. It was a dummy and how you notice that was seeing the same thing back at the Ruins.. Then the dummy turn red "Hey stupid bag of flesh!" You jumped in shock well not literally anyways you were scared it was talking then what scares you more was that the dummy was turning red and it looked pretty mad "CAN YOU LISTEN?!" You shivers from this fear and anger "y-yea i can.." Then everything went grey then went back to normal to see your soul was out of your body and from there you knew a fight had started this scared you. "DUMMIES ATTACK!" You then saw multiple dummies that were small coming to you and it threw what seem like cotten and you dodge it.. Sheesh this was already harder then you thought.. Fuck you should have moved on and never came to Undyne place and now cause of that you had to walk back to Alphys.. You regret that choice as you then saw it was your turn

"Hey lets not fight and no one gets hurt!" "*Seems like that didnt work" That voice.. It getting louder and closer eveytime im in battle... Wonder what it is.. I ask Flowey about it. You then dodge but as you dodge the attacks of the small dummies hit the Mad Dummy.. "*Use their attacks against the other one stupid!" ... Yay another mean voice! You did what it said and it helped you.. Then it turn out he replace his old dummies to robot dummies that shoot rockets.. FUCK YOU "AHHH!" You ran around dodging the stupid rockets as you ran you heard Dummy saying and laughing "ahahahaha Die Die Die!" You dodge and it was your turn you did the same thing and that didnt work "Oh come on!" you dodge and try the same tatic as the rockets hit the dunmy and course it get mad as it replace the dummy "I DONT NEED THEN I JUST USE THIS!" Dummy threw a knife and you just step to the side "UHH....... WELL THEN I JUST!- Wait what?! Acid rain gah!" Mad Dummy ran away and from there you saw Napstablook what was werid that Napstablook was looking at you "good thing i came i just wanted to say thank you again and wanted to meet your new 'friend' anyways be careful" You nodded and Napstablook left and you looked over at Flowey "Well lets keep going!" Flowey nodded as you sigh softly and continues to move on it seem peaceful till you tripped and fell on the ground. Good thing it wasnt on the garbage water anyways you got up and looked behind you to see what tripped you and you a brick with a letter to it.. This was creepy.. You picked up the letter and open it to see who wrote it and for the sake of your living you hope it wasn't a trap.. Then you notice something... It had your name.. You started reading it. "Dear..
