She looks uncomfortable. "They definitely communicate with each other, and they can definitely understand their Trainers to some degree. ...I've heard of one human who claimed to be able to understand Pokémon, but... well, people say a lot of things."

"Oh, well, tomorrow I should prepare a Comprehend Languages, I guess!" If she pets Wooliam on his face and not his wool does she get zapped.

Nope!

(She looks really uncomfortable about that idea, but doesn't say anything.)

Oh good. About the facepets, not the discomfort. Facepets for Wooliam. "What do I need to know about showdowns with wild Pokémon that wasn't in the movie? Wild things on Golarion people sometimes address with their own companions but it's actually more common for people to fight them personally, sometimes people who aren't any good at that like me hire help to guard them."

"If you wander anywhere where a Pokémon might be hiding — like that tall grass over there, or a cave, or any place with good hiding spots — a wild Pokémon might attack you. If you send out Wooliam, you can — I'm sorry, I've never explained this to an alien before — you can give it instructions about what moves to use. Right now, it knows Growl, which makes the other Pokémon worse at physical attacks, Thunder Wave, which can paralyze the other Pokémon, and Tackle, which is pretty much what it sounds like, but it'll learn more as it gets stronger. You can either have it knock the other Pokémon out, or try to catch it.

You might also be challenged by another Trainer — that was in the movie too, I don't know how obvious it was. That's pretty similar to fighting a wild Pokémon, except that most Trainers are better at giving instructions than most wild Pokémon could manage on their own.

It's a good idea to keep a Revive on hand in case your Pokémon gets knocked out, and some healing items to replenish its health — both are legal to use in battle, too, but spending a Revive to win a battle is almost never a good idea unless you're a professional Trainer who can afford it.

If it's getting dark, you can ask just about any house to let you sleep overnight, and they'll let you.

When you're travelling and aren't in a battle, it's normal to keep your Pokémon in its Pokéball, like so."

She presses a button on a red-and-white sphere. 

There's a flash of light, and Wooliam isn't standing there anymore.

"Do channels not work? I get six of them a day."

"...I think that word means something different in your language." She is struggling to understand how TV channels would be relevant here.

"Oh, the kind of healing that comes in a burst instead of at a touch."

That's not really how she thought healing worked but she doesn't personally know how to do it without items. "If you can heal them yourself, that should be fine, though if you're battling another Trainer you should wait until the battle is over to do it, and it would be polite to heal their Pokémon as well."

"Okay. And Wooliam will be plenty to get me from here to a city?"

"It should be, as long as you're careful. If you're worried you can always try catching another Pokémon on the way."

"How does that work?"

"Follow me, I can show you." She heads over to the tall grass.

Laia follows along.

"So, first, you're going to want to walk around in the tall grass until a wild Pokémon attacks you." She does that.

Eventually, a yellow duck jumps out, clutching its head!

"You want your Pokémon to wear it down a bit — don't actually knock it out, though, the Pokéball won't be able to properly register it. If you can paralyze it, or anything like that, that helps too."

She sends Wooliam out of the Pokéball and demonstrates this. Laia might pick up a bit more about the process of giving a Pokémon instructions in battle, as practiced by people who are not movie characters.

Eventually there is a tired-looking Psyduck in front of her.

"Once you're ready, throw an empty Pokéball at it. It might take a couple tries, let me see—"

There's a flash of light, and the Psyduck disappears.

"And there you have it! Any questions?"

"What happens to the duck Pokémon now?"

"...Well, I don't actually need a Psyduck for anything, so I'll probably release it back into the wild."
