A/N: Rated k. sorry for the long update.

The first thing Chara noticed about Waterfall was how surreal it was. with its glowing plants and rivers cutting through the darkness, it was hard to believe such a beautiful place could exist. They told Asriel this, and he agreed. They stopped to examine a strange flower with glowing blue petals. However, when they touched it, it spoke:

"Gerson, look! I'm gonna beat up this bad guy!" The child pulled their hand away and looked around. There was nobody there. They touched the flower again, and it repeated itself. How strange! I wonder how it does that!

"That's an Echo flower. When you touch them, they repeat the last thing it heard," Chara jumped at Asriel's voice "Don't sneak up on me like that!" They exclaimed. "So, do Echo Flowers always grow like this? They sure are tall…"

"I don't know. But I bet Dad does! He likes plants,"

The children continued walking, Chara touching the Echo Flowers and listening to bits of conversation. The first one they came across was pretty funny. Apparently, someone named Undyne tried to beat up the mailman! Most of the conversations they came across were meaningless. But one stood out to them.

"Did you hear about the kid who fell Underground?"

Of course, who hasn't! I mean, they're the angel in the Delta Rune!"

"I'm glad they fell. We've been here so long… I didn't think we'd ever escape. But we finally have a chance…"

Chara stopped. I'm an… angel? I've never had anyone say that about me. "It's true," Asriel spoke quietly "Maybe you don't think that highly of yourself, but to us Monsters, you're a fallen star that carries everyone's dreams!" His eyes seemed to light up as he said that, like he truly believed it. "Oh… sorry, I got carried away. I know how difficult it can be to feel like you can't let anyone down…"

"It's okay. C'mon, I want to explore more!"

Soon the children reached a place where huge piles of garbage stood. "Asriel, what's this?" the human asked. "This is the Garbage Dump. When humans throw stuff away, sometimes it ends up down here. You can find really neat stuff If you know where to look!" Typical of humans. So wasteful. Chara took off their socks and shoes, then waded into the dirty water. "Wait, Chara! Mom doesn't like us going there!"

"I'll be fine! Just give me a second!" They climbed the nearest trash heap, debris coming loose and tumbling to the water. One bit of said debris hit them on the head, nearly making them lose their grip. "OW!" they cried, looking for the offending piece of trash. However, they saw something much more eye-catching. Floating in the water was a small keyboard. Immediately, the child jumped off the trash heap, causing a splash. They quickly snatched up the instrument and held it out. "Asriel, look at this!" they called, heading towards the shore. The goat looked at his friend and giggled. Chara was soaking wet and dirty; but their eyes were bright as they held their prize high.

"Cool! Does it work?" He asked. Chara shrugged and tested out one of the keys. It made a noise, but it was muffled and out of tune. Chara seemed to deflate like a balloon, shook the instrument and tried again. "Hey, it's okay," Their brother said "I bet Mom or Dad can fix it!"

The other child nodded "Let's find them," They said. It seemed they were determined to get the keyboard fixed as fast as possible. "We should tell them that funny story we heard in the Echo Flowers, too!" Asriel replied, laughing.

When the children reached their parents, who were in the cave behind them, Toriel took a look at the keyboard. "I'll get someone to tune it when we get home" she said. "I just wish you hadn't jumped into the water to get it…"

"I'm fine, Mom,"

"Okay, Child. But do tell me if you start to feel ill,"

The rest of Waterfall was uneventful, and when the Dreemurrs went home, Asgore called somebody to fix the keyboard. "I'm glad you're feeling better now, Chara," He said at dinner "You seem much more cheerful than this morning,"

The next day, when the keyboard was fixed, Chara could hardly wait to try it. They pressed an experimental note, which came out much clearer than at Waterfall. They played songs they remembered, then made up tunes. "Wow, Chara, you never told me you could play piano!" Asriel said.

"My father taught me…" They said "Look, Asriel! I made a song for you!" They quickly changed the subject. "It's simple, but that just means you can add a lot of stuff to it!" Chara played the song, which Asriel loved. The children spent the rest of the day making up songs and playing them on the keyboard. The Dreemurrs soon got Chara new instruments to play on, but the child's favorite was always the one they got from Waterfall.
