Waterfall

(Y/n) and Frisk soon entered the place known as Waterfall. (Y/n) looked at her surroundings. She saw multiple waterfalls from behind, and ahead she saw three monsters. One was a yellow monster with yellow stripes, who looked to be staring at the water, another one was an orange fish looking monster, sitting next to a blue flower. And the last one they knew well by now. It was Sans, sitting at his stand. (Y/n) and Frisk smiled at him. And close to the monster and flower, was another star. (Y/n) went up to it and touched it. Frisk followed. (Y/n) hear the voice again. "The sound of rushing water fills you with determination."

(Y/n) and Frisk approached the yellow monster staring at the water. "Yo! Are you sneaking out to see her, too? Awesome... she's the coolest, right!? I wanna be just like her when I grow up... Hey, don't tell my parents I'm here. Ha ha." The monster said. (Y/n smiled. "No worries, kiddo." She said. "Yeah, we won't tell." Frisk added. The monster smiled, then went back to staring at the water. (Y/n) and Frisk went to check out the flower. The monster next to it then spoke. "This is an Echo Flower. It repeats the last thing it heard, over and over." Frisk touched the flower. "This is an Echo Flower. It repeats the last thing it heard, over and over." It echoed. "Neat huh?" The monster asked. This time (Y/n) touched the flower. "Neat huh?" It repeated. Frisk chuckled and (Y/n) smiled. (Y/n) and Frisk walked up to Sans, who grinned once he saw them. "What? Haven't you seen a guy with two jobs before?" He asked. "Fortunately, two jobs means twice as many legally required breaks. I'm going to Grillby's. You guys wanna come?" He asked. "Sure." (Y/n) said.

"Well, if you all insist. I'll pry myself away from my work." Sans got up and walked toward them. Sans began to walk in the opposite direction. "Over here. I know a shortcut." He informed. They followed him. Soon they were already at the restaurant. "Fast shortcut, huh?" Sans asked. "Hey, everyone." He greeted. Everyone turned and greeted him back. "Hey Sans, weren't you just here for breakfast a few minutes ago?" A bird monster asked. "Nah, I haven't had breakfast in at least half an hour. You must be thinking of brunch." He said. Then he winked and everyone laughed. "Here, get comfy." (Y/n) and Frisk sat down on chairs at the bar. (Y/n)'s eyes widened when she heard a loud sound and looked down to see another whoopee cushion on her seat. Frisk snickered. (Y/n) turned to give Sans a look. "Oops. You might want to watch where you sit down. Sometimes weirdos put whoopee cushions on the seats." Sans said. "Weirdos huh?" (Y/n) asked sarcastically. "Yup. Anyway, let's order." Sans said. Whaddya what?" Sans asked.

"A burger for me." (Y/n) said. "Me too!" Frisk agreed. "Yeah. I think I'll have one too. Grillby. We'll take three burgs." Sans said. The fire monster went into the back. Sans turned to the girls. "So, what do you guys think? About my brother?" Sans asked. "He's awesome." (Y/n) said. "Yeah he's pretty cool." Frisk said. Sans lit up. "Of course he's cool. You'd be cool too if you guys wore that outfit everyday. He'll only take that thing off if he absolutely had to. Oh well. At least he washes it. And by that I mean he wears it in the shower." Sans said. Sans snickered when (Y/n) and Frisk shared a grossed out look. Grillby came back with the food. (Y/n) took the burger with both hands and began to eat it. Sans picked up the ketchup. "Here comes the grub." He turned to (Y/n). "Want some ketchup?" He asked. "Sure." She said. "Bone appetite." Sans said. (Y/n) took the bottle and all of the ketchup came out and onto his food. Frisk was trying not to laugh and (Y/n) looked peeved and turned to Sans who was snickering. "Great joke Sans. What are we, six?" She asked sarcastically. "Whoops. Aye, forget about it. You can have mine. I'm not hungry anyway." Sans said, pushing his burger over to her.

"Oh. Well. Thanks, I guess." (Y/n) said. "Anyway, cool or not, you have to agree Papyrus tries real hard. Like how he keeps trying to be part of the Royal Guard. One day, he went to the house of the head of The Royal Guard, and begged him to let him be in it. Of course, she shut the door on him because it was midnight. But the next day, she woke up and saw him still waiting there. Seeing his dedication, she decided to give him warrior training. It's uh... still a work in progress. Oh yeah. I wanted to ask you two something." Sans said. Suddenly the lights tuned off except for where they were sitting and Sans turned serious, which was out of character for him, so they tensed. "Have you ever heard of a talking flower?" Sans asked. Was he talking about Flowey? "Yes..." (Y/n) said slowly. "So you two know all about it. The echo flower." Sans said.
