Toriel was doing her best to call everyone to order; but with dozens of monsters all chattering and wanting to spread out, she had her work cut out for her. Frisk did their part to help, small as it was; they'd talked to Greater Dog and Lesser Dog, who were unclothed and running around, excited and barking, looking like actual dogs rather than monsters- at least, until Lesser's dog neck started to extend. Doggo had helped them translate and they'd reached an understanding- they were to wear leads and act like actual dogs in areas where it may be notable for a dog to be loose. Doggo's seeing eye dog was by far more placid than any dog monster, sat by his side panting and ready.
They called them both over- Greater Dog stopping just short of bowling them over- and they attached leads to the pair of them. The pair of them were perfectly happy to stay by their side as long as they got regular attention; and Frisk knelt and petted them both as Asgore came off the bus, stepping casually over Lesser Dog's extending neck as he waded into the crowd. A small human family watched from a distance.

"All right, everybody!" His booming voice carried further than Toriel's gentle one and everyone turned to look at him- although some, such as Undyne and Papyrus, needed to notice the quiet surrounding them before they fell quiet themselves. "We all need to stay together, now- no getting lost, okay? Do not wander too far, and make sure someone knows if you leave the group!"
He was surprisingly serious as he spoke, and Frisk could see how he'd been a respected king. There was a long pause; then the stern demeanour broke and he grinned. "Shall we head to the beach?!"

A roar of approval filled the air; a few startled seagulls nearby took to the air as Asgore led the way. Papyrus was always happy to be given jobs to do, and he helped Toriel keep an eye out to make sure nobody wandered off before they reached the beach.
It didn't seem likely; everyone was eager to head onwards. They wound through the tiny village, the collection of rustic hotels and gift shops outnumbering the houses. They all stopped to exclaim over a stream boarded by a drystone wall, alive with waterfalls, reeds and ducks, before following it onwards, down a steep hill.
The road ended at steps directly to the sandy beach. It was a beautiful cove; the land circled around, and the sandy cliffs were topped with vibrant green. Frisk took a deep breath of the sea air; everyone was silent, drinking in the view, the heat, the sea breeze.

Greater Dog was the first to break the silence; he let out a booming bark, and the group laughed and started moving again.
It was the middle of the human's school term, so the beach was almost deserted before the monsters spilled out onto the warm sand. Undyne whooped and sprinted straight into the ocean; before turning around and bounding straight back out, yelling about it being cold. Frisk laughed, heading off to one side and kneeling down.
"You guys did good," Frisk said; the dogs tripped over each other to lick their face at the compliment. They giggled and managed to calm them.
"Remember not to wander away from the group, and don't go too far into the sea," they said, as they unclipped their leads. "Have fun!"

Lesser Dog was off straight away; bouncing straight past Undyne, who was wading cautiously past her ankles, not stopping until his paws couldn't touch the bottom and he swam, back and forth, grinning as many monsters laughed. Greater Dog, however, stayed near Frisk as they rubbed behind his ears.
"Don't you want to go and play in the sea with Les?" Frisk asked. Greater Dog let out a bark and nuzzled into their hand, happily. They smiled.
"Well..." Frisk pulled their bag off their back and thrust the leads into it before rummaging, pushing Greater Dog's nose out the way as he tried to see what they were up to and obscured their vision. Finally they pulled their hand out. "How about this?"
They had a ball in their hand, bigger than a tennis ball and rubbery. They'd got it for this purpose, knowing how much Greater Dog loved to play- and he instantly barked and backed off, tail wagging wildly and his eyes on the ball. They laughed.
"Okay, Grey- do you want to get it out of the water for me?" He barked again, running towards the edge of the water, before turning to watch Frisk walk over.
The ball had a good weight to it; they lobbed it, and it went far enough for him to splash Undyne- now waist-deep- as he chased it; then he was swimming, desperately trying to snatch the ball up but getting a face full of seawater instead. Frisk giggled as he snorted and shook his head; then tried again, succeeding. He headed back over to the shore, looking shrunken as his dense, fluffy fur hung, streaming water onto the sand. Frisk accepted the ball and threw it again; and Grey was off.

"Hey- hey, like, Frisk!" They turned to look at a pair of monsters they didn't recognised. Tall and broad, wearing Hawaiian shirts and eating nice cream; one looked somewhat like a rabbit, furred and beaming. The other reminded Frisk of a reptile- maybe a gecko, smiling slightly at the rabbit, scaled cheeks tinged.
"Heyyy, man, it's good to, like, see you here!"
"Um." Frisk glanced from him to his companion. His voice was familiar, but... Frisk glanced at the other's scaled arms. He had fins on his head, almost like... A dragon?
A dragon and a bunny!
"Oh!" Frisk realised and beamed at them. "You two were the royal guards!"
"Like, yeah, bro! That's us! Man, I owe you, like, so much. Things are so awesome now and it's 'cause of you." The dragon smiled and nodded at Frisk. "Oh- hey, your buddy's back. We'll leave you to it, but we just, like, wanted to say thanks and stuff."
"...Thanks", the dragon monster echoed as they left. Frisk beamed at their backs before turning back to Greater Dog. He was panting around the ball, and Frisk took it and threw it back into the sea for him.

"Come on, Frisk!" Undyne called. "Come in the water!"
They shrugged and pulled their sandals off. Leaving them a short way from the water's edge, they stood on the wet sand and let the next wave wash over their feet. After the heat of the day it felt colder than they would have guessed and they gasped; but stayed still until the water receded. Then they took another step, letting the next wave wash over their ankles.
Greater Dog returned with that wave, and Frisk gave him a rub on the head as he gave the ball back, beaming with pride. They threw it again- and with their attention off the water, they were taken by surprise by a much larger wave splashing half-way up their shins.

They let out a shriek. Undyne laughed and called them further in; shrugging, they waded further, until the water was up to their knees. Undyne- wet now up to her shoulders, and stripped to a sports bikini- came over.
"Come on, punk, let me take your bag to Asgore and you can come in!"
"Oh- um... I was just going to stay on the sand," Frisk said, looking awkwardly around for their parents. They were sat on the rocks by the cliffs, talking together. "I, uh, don't want to disturb them."
"Nah, it's fine, I'll just drop it over there and come straight back!" Undyne was tugging at their bag now.
"W-well, I mean, I just- I, um. I can't swim," they mumbled, feeling their face warm. Undyne blinked, then shrugged.
"So don't go that far in! I'll keep an eye on ya."
"Oh- well- I... Oh, fine." Frisk sighed, handing over their bag and grabbing the hem of their sleeveless t-shirt. They paused. "Are you sure? I don't mind staying on the shore..."
"Come oooon!" Undyne shook their bag at them and they groaned, pulling their t-shirt over their head. No sooner was their ponytail free of it than she snatched it from their hand and ran over the sand, picking up their sandals as she ran.

They felt hot in the face, wrapping their arms around their torso. The monsters had spread out; Papyrus and Sans were digging in the sand, with Alphys playing games nearby. Toriel and Asgore barely glanced over when Undyne dropped off their stuff. Nobody was paying any attention to them.
Actually, someone was. They glanced around in surprise at Greater Dog, waiting patiently, ball in his mouth.
"Oh... Grey, I'm sorry!" They let their hands fall and knelt by him, fussing him with one hand while taking the ball. "I was distracted by- eep!"
A wave took them completely by surprise; washing over their legs, they landed on their backside on the sand and sucked in a deep breath at the cold sea water. Greater Dog quickly snapped up the ball back up before it could be washed away.

"That's one way to get you in the water!" Undyne was chuckling behind them. Frisk paused, then started laughing as well.
"Okay- let me throw the ball for Grey and I'll come further in!" They stood up, taking the ball again and giving it a good throw. As Greater Dog bounded after it, Lesser Dog paddled over to where it had splashed into the water. Frisk watched as he circled it, waiting for his friend.
They started to walk further in. Now that they were wet, it wasn't too bad- but any part of their body that wasn't wet was still difficult to get in the water, and they squeaked when the gentle waves reached their lower belly and stopped.
Undyne shoved them gently on the shoulder. "Keep going!"

Frisk looked at her, took a deep breath, and dropped. They let themself fall completely into the water; it covered their head for a moment, before they bounced back to their feet, gasping.
"Ohgod that's cold!" Undyne started to laugh again as they brushed errant strands of soaked hair off their face. "Okay. Okay, okay, I've done it- I can go further now." They kept up with Undyne as she strode further in; stopping when they had to stand on tiptoes and the water reached their chin.
"Come on, Frisk- take my hand, I'll take you in further!" Frisk nodded; both of their hands took one of hers, and they kicked with their legs as she moved in until the water was up to her chin.
"How's that?!"
"Um. It's okay!" Frisk kicked and wiggled, moving their hands up to her shoulders and moving around her. "Ah- hehe, okay, this is nice."
"When we get back, I'll teach you to swim," Undyne promised. "Then we'll come here again!"

There was a pool in the lower area of town; Undyne had insisted on it being built, but it had proved to
be popular, especially as spring had taken hold. Frisk had never gone, though. They spluttered as a small wave splashed their face and nodded. It would be much more fun to actually be able to swim with their friends instead of having to hold onto them.
They stayed out like that for some time. Onionsan came to say hello, promising to help watch for any monsters who had trouble, before swimming off- she was clearly thrilled to have company, and on the whole she was obviously so much happier out here than she had been Underground. Undyne stopped to wave wildly at Alphys, who had sat near the edge of the water to watch them swimming and playing together.
"You good to head out, Frisk?" They nodded; Undyne was clearly ready to see her girlfriend, and they were starting to shiver.
They made their way to the shore- Frisk letting go of Undyne as soon as they could touch the bottom. They were thankful for the warm sun on their wet shoulders and hair; they raised their arms so they could feel the heat caressing their skin.

This had been a great idea.

I tried to post this chapter this morning on my phone, and accidentally posted the next chapter. Whoops! Sorry if you saw that.

Too bad Undyne doesn't get to really swim with her friends- but I'm sure she won't waste the opportunity to swim by herself.
