Water falls here

"Well, that was really nice. But are you sure you will be able to do it? Free all monsters?" You continued onwards past the foggy area of snow to solid ground, A small river next to you with ice blocks passing by one by one "Well I'd never make a promise that I can't keep" As you walked you entered a small area with Monster Girl, A new kind of girl and Sans behind a station. You walked up and tapped the desk of the station "So is this also your work as a sentry Miss "I can teleport" Sans laughed and winked "Nah, I work part-time as a watch guard for the sentry and for Waterfall to make sure no one falls in If you sea what I'm saying" You chuckled "Yeah I get it." Sans walked out the side of her station "Hey I was about to head over to Grillby's. Wanna come?" You nodded "Ok, But you mind paying?" You walked up to her "Not at all. Any reason why?" Sans walked past you "I haven't paid my tab yet. Come on I know a short cut" You followed Sans but ended up in an endless hallway with a single grey door "Huh that's strange. Maybe that's the short cut Sans told me about" You waited for a response but Frisk and Chara weren't there "Guys?" You walked up to the door "What on earth..." As you opened the door there was a showy figure in the distance "Um...Hello?" You walked towards them, Quivering a bit in fear as the door behind you shut "Look Sans if this is another joke it's not-" "Sans..." The figure spoke "Um..." Black gooey tentacles grew around the figure "You will make a fine specimen" The tentacles wrapped around your feet and arms as it pulled you towards the now able to see the female figure as they wrapped their tentacles more and more around you. They slowly unbuttoned your pants when

"AAH!" You shot up! Sans sliding a cup of water towards you "You ok? Kinda passed out on me there, I guess since you're the first human to take one of my short cuts you would be in a state of shock" You drank out of it as Grillby slowly moved a burger towards you "(Feel better)" You smiled at Grillby and took a bite out the burger while Sans drank out a bottle of ketchup "What happened? You kind of dozed off the moment you followed Sans?" Frisk moved her hand into your chest "Oooh I'm sensing a lot of fear...Was it some kind of nightmare?-" "L-look I'm fine! I'm fine...Just must've dozed off the moment we walked onwards." You thought to them as you ate "Hey, What do you think of my Sister?" "Pretty awesome, I love all the adventures I have with her!" Sans chuckled "Mhm, She is pretty cool, Especially with that outfit, It was meant to be for a costume party but she hasn't taken it off since I mean she only does it if she absolutely needs to...For maybe someone, she's close with" You were completely clueless to this, You were just happy to get a burger "Um heh, Anyway. She does wash it...By that I mean she wears it in the shower" "Gross" Sans nodded, Grillby offered you some ketchup "No thanks Grillby" Sans held out her hand "I'll take some-" "I WASN'T ASKING YOU!" Grillby put the bottle back and walked off to the backroom "Man dude, You've gotten some real attention, I haven't seen Grillby like that since well...never." You sighed and swallowed the burger "Look I never asked for attention, I just accidentally fell down and ended up here, And as nice as it is I have a life on the surface. A nice life...With a Mom, A Dad (Optional Siblings if you have any) and all that. Up there I'm never this popular and I've been rushing through to get back home" Sans put her bottle down "Maybe you should slow down, About 500 monsters live down here and we've been here for years so why not try to see the things we find fun down here as much as you find fun things up there" A spark awoke within you. You sat up "Yeah...Thanks, Sans, I'll do that" Sans poked your shoulder "Oh and one more thing Since you're kind of my best friend now. Call me anything you like, Paps likes to call me Lazybones so I call her Stroppy shorts. Since she's stroppy and wears shorts" You thought "How about...Joker?" "YOU GET WHAT YOU FUCKING DESERVE-" Frisk tried her best not to laugh her ass off "Hm, Joker. Sounds nice-" "I changed my mind" Sans looked at you and laughed a bit "Oookay then." "Hmmm...How about I call you Sansy? But only when we're alone." Sans and You made the way to the door "I like that" 

You walked out to see Sans was gone but you were outside Grillby's "Didn't even take me with her."  You sighed and walked back through the way you came. As you passed Sans' station you saw a waterfall with bits of ice blocks falling down it "Huh, dunno what I expected from a place called "Waterfall". Welp let's see what this has to offer" You made your way down a separate path where 2 more pathways led down and ahead, in the distance you saw a blue flower of some kind. You took the lower down way where no Ice fell "Coward" "I think I deserve that after all the puzzles I went through with Papyrus" Frisk nodded at your point as you walked up to the flower "I swore I saw something...Behind that rushing water..." You looked around "Huh!? Who's there!?" "Huh!? Who's there!?" You turned back to the flower "Can you talk?" "Can you talk?" "Well, Of course, I can talk!" "Well, Of course, I can talk!" You rubbed your head in confusion "I think it's kind of like an echo canyon. You say something and it repeats it" You began to walk back to the original pathway "Well that sounds a bit like something for loners to talk to" "Why aren't you talking to it then?" You glared at Chara "Because I have 2 strange Ghost girls following me" You pulled up your trousers and walked across the waterfall while avoiding the ice blocks. 

On the other side, it was shadowy, the light from the last area worked at the only light for this area as you looked at your hands "Woah, I look so ominous" You kept walking but stopped at the tall grass and sniffed "Something smells of fish..." Chara entered your body and sniffed a bit as well "I smell it too" Finally Frisk took a sniff before giving it back "Must be a fish nearby?" You wondered "Well it'd make sense, Maybe there is some kind of water stream leading down into the underground and that is where fish come from into the underground here." "That's pretty smart" Frisk twirled her hair around her finger "Oh thank you" She blushed as you walked through the tall grass you saw something on your left. An opening. You saw Papyrus and some shadowy figure with armour on. You walked over and peeked your head out the grass to watch "H-hi Undyne! I'm here with my daily report!" You heard Papyrus say in her high optimistic voice, "Uhh...regarding that human I called you about earlier..." There was a low mumble from the shadowy figure known as Undyne "Huh? Did I fight them? Y-yes Of course I did! I fought Valiantly!" Another low grunt "W-what? Did I capture them? Um well...You see...Since it's a male Human and we've never seen one down here in basically never. And since I fought them. Maybe you should fight them! They are a really good fighter and-" Papyrus noticed your face in the grass "...A-and..." You quickly backed away into the grass as A mumble came from Undyne "Well...I thought you would like to fight them! Y-you, do like a good fight Undyne." Undyne nodded and gave Papyrus one last mumble which you assumed told her to leave because Papyrus saluted and left right after "Man...Papyrus seemed really nervous around that guy." You nodded and kept walking when you tripped over something and hit the floor making a loud thump! You heard the metal footsteps of Undyne closing in as you saw the Monster Girl face planted the ground and you were on top of her "Shhh!" You whispered for the Monster Girl to keep her mumbles down. She did just that and Undyne disappeared into the darkness. You got off her and walked out the grass panting heavily from fear. The Monster Girl following as she jumped around excitedly "Yo! I can't believe we caught Undyne's attention there! Too bad I couldn't see any of it. Must've tripped over a twig or something, anyway! I'll get to see it next time! You coming with?" The Monster Girl ran off but tripped over, You helped her up "Thanks, Cya!" She ran off again as you sighed "Man I can never catch a break..."

You moved onwards and did a pretty nice Flower puzzle which you found a Quiche out of doing so. Then passed through a wishing room "Woah...Do you guys see this? Says it's a wishing room!" You closed your eyes and wished "I wonder what he's wishing about..." Chara scoffed "I don't care. As long as he gets moving soon. And remember our plan ok?" She whispered. Frisk nodding as you opened your eyes and kept walking. Then passed by a room which contained the reasons of the Human attack "Hm...Some kind of Monster and Human war, Pretty sure I remember something like this...When I fell down I had some kind of flash telling me all about that war. Must've hit my head wayyyy too hard" You sat down with crossed legs on a plank of wood which led you across the water to a dock of some kind of the other side. As you kept walking along the wooden ground a blue glowing spear stabbed in front of you as you froze in fear "Look!" You looked over to the left and saw Undyne! She summoned another spear and threw it towards you
