"Well, here we are in Coumarine," Clemont said. "Have you decided who you're using, yet, Ash?"

"Well, not Goomy," Ash replied. "Not yet, he's too new and I wouldn't want to spring that on him. But, hmm… it depends what the rules are for this gym!"

He looked around. "Actually, where is the gym?"

"That's something special about Coumarine," Clemont told him. "It's actually in two halves, connected by a monorail – see, just over there!"

Ash looked.

"That's two rails, though?" he said. "Why is it a monorail if it's got two rails?"

"It's because each of the carriages only uses one rail," Serena said. "I… think?"

She glanced down at Fennekin. "I've always just thought of them as monorails."

Fennekin shrugged. "Don't look at me, I'm technically a rough-terrain Pokémon and we don't have those."

Serena tried to stifle a giggle. "Didn't you grow up in Professor Sycamore's lab?"

"I'm very in touch with my roots," Fennekin said, flicking her tail.

"So does that mean something that uses magnetic levitation would be a none-o-rail?" Ash inquired. "Since it wouldn't use any rails."

"...now I'm thinking about that as well," Clemont sighed. "I think it's just called a monorail because it sounds cool, even though it's not the only thing that uses one rail."

"Sounding cool is a good reason," Ash said. "What about the, uh… is it a Contest Hall? It can't be because you don't do Contests there."

"I think it's called a theatre!" Bonnie told him.

"How are you spelling that?" Arc asked.

"I'm not, I'm saying it," Bonnie replied.

"That's fair," Pikachu said.

"We should probably just go and queue for the monorail," Clemont said. "Especially since I saw a sign saying the Pokémon Centre was in the other half of town as well."

"Or," Arc said.

And they were in front of the Pokémon Centre.

"Aww," Bonnie said. "I wanted to see what it was like going on the Monorail!"

"Sorry," Arc said.

And they were in front of the monorail station.

"I think I'm dizzy," Clemont said. "Which monorail station are we at? Wait, don't take us to the other one!"

"I am quite capable of landing you at the correct monorail station," Arc told him. "You are at the monorail station where you get on the monorail and then you are near the Pokémon Centre at the other end."

"Great!" Bonnie said, unfazed. "Let's see what it's like!"

Overall, it could have been more exciting by being faster, or having a loop in it, but the view was great and it dropped them off not far from the Coumarine Pokémon Centre and Coumarine Gym.

When they reached the Pokémon Centre, though, they found that the front counter was staffed by a Joy looking like she quite wanted sleep.

"Good afternoon," she said, then yawned. "Oh, dear… sorry, we were helping a Vanillite and it's meant long hours. We just need to know where to send the poor dear back, now, but how are we going to solve that?"

"Using the Clemontic Super Convenient Pocket Size Flashback Analysis Projector!" Clemont said, taking it out of his backpack.

"Magic?" Serena asked. "If they've got older relatives then that might work."

"Asking them?" Ash suggested. "They might know enough to get started."

"Or you could ask some local Pokémon to help!" Bonnie said. "If you ask all the local Fletchling to fly around asking if someone's missing a Vanillite, then that could work if Vanillite is a wild Pokémon!"

The Joy blinked a few times, then held in another yawn. "I was… not expecting answers to that. Especially not that many answers."

A combination of the methods from Ash, Bonnie and, eventually, Clemont got the Vanillite back to their family – with additional steering from the grumbling Zygarde as they got to the cold bit – and then on the way back down Ash met the local Gym Leader, Ramos.

Ramos was an elderly man with a large collection of Grass-types, both for Gym use and at the ranch that sprawled over the hills around Coumarine, and he looked Ash up and down a bit before nodding in consideration.

"A three on three battle, I think," he said. "Tell me, sprout, what do you know about gardening?"

"Sprout?" Pikachu repeated, then flicked his ear. "Huh."

"Well, I'm not really an expert," Ash replied. "I did grow some Gracidea at home, though."

"Gracidea?" Ramos repeated, surprised. "That's not bad, they're quite fiddly plants. But I've watched many of your battles, and your Shaymin never seems to go into Sky Forme."

"Yeah, he doesn't really like doing it," Ash agreed. "It's okay, I wouldn't force him."

"Well, then…" Ramos said, thinking. "Take my advice, young man. Some plants get on well in wet soil, but for others it's a problem, and what's best is that your garden has well-drained heights and wetter lower areas. That way, you can grow all the plants on the land that suits them best. What do you think of that?"

"It's like taking care of Pokémon, right?" Ash asked. "Every Pokémon has their own preferences, and it's way better to make sure they all have a niche which fits rather than try to set up one place that they're all sort of okay with."

"You'll do," Ramos said. "Come on, let's have that challenge. Oh, and I want to see how your Kalos Pokémon are growing, so use at least one of them."

"You've chosen your Pokémon?" Ramos checked, then held up a Pokéball. "Jumpluff, you first."

"Here we go!" Ash said, expanding out a Moon Ball. "Go!"

Clefairy appeared, wings fluttering as she held herself in mid-air.

"Bonjour," she said, with a little mid-air bow. "Je serai votre phobie du jour."

"My word!" Ramos said. "That's an impressive Pokémon, sprout – I knew you could understand Pokémon, but I didn't know you had any where anyone could understand them."

"What's he talking about?" Serena's Ponyta whispered. "Can he understand Clefairy? I can't understand Clefairy."

"Of course he can," Clemont replied. "Why wouldn't he?"

As Ponyta tried to work out how to put it, Ash pointed. "Let's start with a Metronome!"

"Watch out, Jumpluff," Ramos replied. "Sunny Day!"

Jumpluff pulsed, making sunlight shine through the branches framing the open-air gym arena, and then Clefairy lunged forwards with her fist glowing. "Voila!"

Ramos' Jumpluff did a twirl to get out of the way, the attack only scoring a glancing blow, but Clefairy flicked gravity around to avoid wasting the momentum and did another Metronome. This time it turned into a Zen Headbutt, and she slugged Jumpluff hard enough that the bouncy Grass-type went oof backwards.

"Solarbeam!" Ramos called. "You know, sprout, I asked for how your Kalos Pokémon are growing, and I didn't realize that an old stalwart like your Clefairy's from Kalos, but that's me told."

"Actually, she's not from Kalos," Ash explained. "She's actually from the moon."

"Huh?" Ramos said, then looked up at where the moon would be if it was overhead. "Explains a few things, I suppose… can't grow much on the moon, though."

"That depends if you're in Mew's greenhouses," Ash replied. "Great work, Clefairy!"

Her latest Metronome had become Psycho Cut, and she spent several seconds chasing Jumpluff around with a psychic sword from one arm before the attack wore off.

"Hmm," Ramos mused. "Bounce!"

Jumpluff bounced off the floor, then off one of the trees, and another – speeding up each time, and whirling their three cotton puffs through the air to try and hit Clefairy. The first time they made contact, it knocked Clefairy into the floor with a squeaky Uff!

"Hang in there, Clefairy!" Ash called. "Me First!"

Now both Clefairy and Jumpluff were bouncing around at increasing speed, with each impact between them sending the two Pokémon springing off and bouncing elsewhere.

"And… Gravity up, now!" Ash said, suddenly.

Clefairy and Jumpluff smacked into one another again, and this time it sent Jumpluff up and Clefairy down. The reversed gravity dampened Clefairy's impact with the ground, a little, but more importantly it sent Jumpluff floating off into the distance.

"Now, Cosmic Power!" Ash said, as Clefairy got up and wobbled a bit. "And get ready to hit Jumpluff with Stored Power if they come back down again!"

"That won't be necessary," Ramos decided. "Well done. But don't forget to send out a Pokémon who's actually from Kalos at some point…"

Ramos sent out a Weepinbell, and Ash responded with Servine.

"Ah, here we are!" Ash's Grass-type said, doing a twirl. "Lunar Blessing!"

"Acid!" Ramos called, then lifted a hand to shade against the glare as Servine flashed with silver light. "Well, now, you don't see that every day…"

Servine finished doing her twirl, and brought her tail up like a fan before fanning herself with it.

"Not bad, no?" she asked.

"Is this one a Kalosian Pokémon?" Ramos asked. "She's certainly the very model of a Lumiose fashion icon."

"Actually she's from Unova," Ash said. "I think? That's where I caught her, but she was wild, so she could have been an immigrant. I wasn't counting her as from Kalos, though."

He raised his voice. "Watch out for those Poison attacks! Use a tidal shield!"

"Of course!" Servine agreed, sweeping her tail around and drawing water in the air with it. It formed a moving shield which absorbed the impact of Weepinbell's Sludge Bomb attack, tainting it slightly purple but otherwise leaving it unaffected.

"Razor Leaf," Ramos said. "No, Poisonpowder and then Razor Leaf – try and whip it over that shield!"

"Hey, Servine!" Ash called. "Did you know the moon used to be made of molten rock?"

"I did not!" Servine replied, interested, as she dodged artfully out of the way of one Razor Leaf barrage before running up the side of her water-shield in long floaty low-gravity jumps. "Please, tell me more!"

"What is this, sprout, a trivia contest?" Ramos asked.

"It's how the moon got made!" Ash said. "Arc got told the details, I think?"

"Originally the plan was to bring in a separate object to be the moon," Arc supplied. "There was a bit of a crash, and the splashed magma became the moon once it cooled down."

"Ah, so it's intrinsic to the moon itself to be made of once-molten rock!" Servine said.

She did a backflip and a twirl off the very tip of her water shield, then stopped moving and hovered in mid-air.

"In the flame of the moon!" she said, and used Magma Storm.

"Well, at least you didn't set the forest on fire," Ramos decided, recalling Weepinbell who was in no state or mood to keep going. "That's always courteous. Now, third Pokémon for me, and you'll have to switch to a Kalosian one now. Just a reminder."

"Right!" Ash agreed, as Ramos sent out his Gogoat, responding with Hawlucha. "Let's go!"

"I am Hawlucha, the tiger!" Hawlucha agreed, striped mask sitting neatly on his beak. "I'm not sure what a tiger is but it sounds impressive, so Hawlucha is the Tiger today!"

"Are you sure that's a Kalosian Pokémon?" Ramos asked. "That feels like the wrong continent."

"No, definitely from Kalos," Ash replied.

"Well, Gogoat – begin!" Ramos called. "Razor Leaf – and Take Down!"

"Get ready, Hawlucha!" Ash warned.

Hawlucha took his stance, ignoring the Razor Leaf attacks – including the ones that hit him – then reached out and grabbed onto Gogoat's horns.

And used Vital Throw, resulting in Gogoat leaving the ground and not returning to it within the bounds of the arena.

Or the forest.

"Hawlucha has suplexed a trained Pokémon," Hawlucha announced.

"I don't actually think that was a suplex?" Ash pointed out. "They sort of have to hit the ground for that."

"Hawlucha is sure they will hit the ground somewhere," the Fighting-type replied.

AN:

A tiger is like what happens when you take Raikou and subtract dog.

You might need to subtract quite a bit, given her usual behaviour.
