UNDERTALE/Waterfall (Pacifist)

This is the third area in UNDERTALE. If you have seen the Snowdin guide, then this is the next guide. If not, please go back and read the ones you haven't read. Also, Sans has some advice about reading ahead. Don't.

Take A Break, Bro
The first area in Waterfall plays the sans. song, and as it turns out, Sans is sitting there at his stand. You're going to see him a lot during the game. If you don't talk to him, that's fine, but if you wanna take a break with him, talk with him and say yes. There is also a save point here. Save your game. There are a few puzzles that are kinda hard later on. Anyways, continue on.

A Feeling of Dread
There is a puzzle up ahead that involves falling rocks. The rocks knock you off onto a bridge, which leads back to the start. In the middle of the waterfall, there is a secret door that leads to a room with the Old Tutu. Like before, it's the best armor you can get so far. Its weapon counterpart, the Ballet Shoes, are not really useful unless you are a completionist, as well as not available until later. Continue on.

The next area is a hallway with a rocky area overlooking it. After a cutscene with Undyne and Papyrus, we now know 3 things. After walking out of the grass, a small dinosaur monster walks out and says how cool that was. Ignore him, save, continue.
 * 1. Papyrus is working for Undyne against his will
 * 2. Undyne is this murderous knight girl that genuinely hates us.
 * 3. We are in trouble.

Waterfall Puzzles
The next room is easy. There are 4 flowers in an area to the north. They can be used to make a bridge, which is exactly what you need. Line 'em up right, cross the bridge, and continue. The next area is the same thing. The river at the bottom right leads to a good, one-of-a-kind healing item called the Abandoned Quiche. Get it, then use the bell to respawn he flowers, make a bridge to the next room, ignore Papyrus's call, and continue.

The next room has a telescope that gives you a hint to check the wall. Go to the alcove north of the telescope and press A (or whatever button is the confirm button) and a doorway will appear. Look at you go. The next room is a bridge area. Go to the eastern end. At the eastern end, there should be a single bridge tile you must step on to cross. When you step on it, the tile will start moving east. It stops at another bridge. Huh. Odd...

Step forward when you're ready, and a spear lands in front of you. Undyne will appear and start throwing spears. Wow, what a rude person. Run eastward and avoid the spears. Once you reach a patch of grass, she stops attacking. She then goes up and grabs something (hopefully not you) and pulls it up. It's that monster kid again. Whoops.

She puts the kid back down and walks off. Walk out of the grass and MK (monster kid) will walk out and say how awesome that was and that he's never washing his face again. Gross. Go to the next room then come back. There should be a blob at the end of a bridge close to the way you just came back from. He will take you to the room before Undyne's chase. Use this no stock up whenever you need some stuff from Snowdin, as the River Shortcut isn't available yet. Anyways, continue.

Another Mouse Moment
The next room is a save point with crystalized cheese. Gross, but useful. Save and continue. The next room is a hallway, kind of. On the north side of the hallway, nearest to you, Sans is standing there. Don't talk to him. There is a box beside him, however, that you can use. If you haven't already done this, deposit all quest items I told you to save for later into the box. Go through the door on the right of the box and the Nice Cream Man will appear. Yes. Finally, more Nice Cream. Like I've said before, Nice Cream is the cheapest and the best healing item that you can get so far, so get it.

Backtrack to the Sans room. Continue to the pathway at the southeast end of the room (the one leading south). We can't use the area to the east, but the area at the east end of this room is another shortcut for later. This next room is a large maze that you must traverse. The color palette is swapped here, and the maze is also pretty easy. If you go to the area at the west end of the maze, you can get the Ballet Shoes. Not useful at this point, but you can get it for completionist purposes if you like. Continue on. At the northeast end, the path leads to the next area, which is a long hallway. Great... As you traverse the room, a tentacle(?????) appears in the water. Uh... that's not good. Run. After a minute of walking, it turns out that the tentacle belongs to Onionsan. Ignore him. Continue to the next room.

Piano Puzzle
The next room has a path to the north and the east. When you try to go to one of the entrances to either area, a battle with Shyren will happen. This is a scripted battle. All you have to do is ACT and select Hum over and over until she is spared. You can spare her after selecting Hum the first time, but still, the stuff that happens when you continue to select Hum is actually funny. Anyways, that's the only encounter you can do in this room. Go to the eastern one. In this room, there is a piano and a alcove at the north end. To play the piano, you must press the arrow keys (or move the d-pad in the right direction and press A) to play a note. The right notes in the right order will open a secret passage. Here is the combo: Neutral [•], Up [↑], Right [→], Neutral [•], Down [↓], (Neutral [•],) Down [↓], and Right [→]. After doing the combo, a doorway will appear in the northern alcove we saw.

When you enter the room, check your inventory. It's a dog. What the heck?? If you are playing on console, then drop the dog and a hilarious cutscene will play where the dog absorbs the artifact in the room and runs through the walls (it's literally impossible to get the artifact even through hacking), however, if you are on computer, you can hack the dog into your inventory and keep it even after leaving the room or hack it out of your inventory. Either way, the artifact is unobtainable. Backtrack to the room where you fought Shyren, and go to the east. The eastern room is a hallway. There is an area on the northern side of the hallway that has a statue, which has water dripping onto it. The next room has umbrellas. Put an umbrella on the statue and a tune will start playing, and it won't stop. If you listen to the theme long enough, the arrow combo I gave you will appear in the dark area above the map. You happy I'm guiding you? Believe me, this is harder than it looks. Anyways, go back to the room with the umbrellas and continue to the east.

Monster Kid
The next room is a path leading to an area you cannot return from the way you came. Monster Kid will be standing near the entrance. He follows you, occasionally saying something, until you reach a ledge. He thinks for a moment before telling you to climb on his shoulders. He says he will find a different way around and runs off, tripping. The next room starts out dark, but brightens when you reach the save point. Save. This is gonna be hard.

The Killer Fish of The Underground
The next room is a bridge. Uh oh... Go east until blue dots appear around you and spears come through the dots. That's Undyne. Run run run run run. You really don't want to get hit. After getting through that, the bridge... is a dead end. Well that's just peachy. Go back the way you came and Undyne steps forward and breaks the bridge. And there you go. You're dead. It's game over. You can stop reading the guide and maybe do the Genocide Route instead... Not.

Strange Encounter
When you crash land... somewhere, the theme we heard earlier plays while someone starts talking to you. Odd. They know our actual name instead of calling us "human" they start to say their name but the screen fades to white before they say it...
