[Somehow, for whatever reason, be it by Palkia's hand or by the will of Arceus or something else entirely, Ash Ketchum of Pallet Town (with his Pikachu) finds himself in the giant fish tank full of Not Fish Pokémon. Normally one would be alarmed to be displaced in an entirely new world, but for this kid?

>He sees fish.
>He is fascinated by the fish.
>He wants to know more about fish.

So many strange and wonderful creatures swim around and above him that he starts pressing his face against the glass that he can't help but let out a long and audible "Wooooaaaah!!". It's obvious he's deep in awe as his eyes are trailing after the passing stingray nearby.]

Y'know it's too bad you can't catch them like they're Pokémon. I wonder if they can pull off some cool moves...

[All that exploring and sightseeing really works up an appetite for Ash. So of course, the one place he's eager to go next before calling it a day would be the indoor café. He's helping himself with a delightful tuna sandwich and a side of potato chips along with some bubble tea, while his little fuzzy yellow friend sits on top of the table and chowing down on his share. (...Is that even allowed? Doesn't seem like anyone's telling the kid off for letting his pet in.)

Whether you're distracted by the fact his furry companion carries 10,000 volts of electricity in his cheeks, or just... something else entirely, Ash takes notice of you and then your plate which remains untouched.]

Aren't you going to finish that?

[Hint hint, let him try some too?]

[As it turns out, Team Rocket (the whole organized group, that is) has been running this operation behind the scenes, and have been doing shady business — poaching these poor Pokémon from their homes and illegally selling them off discreetly. All the while putting up the front of a marine park.

Ash really didn't like this when word reaches his ears.

So, while the coast is clear and is sure no one else but him and you are present, Ash proceeds to tackle against a locked door a few times. He could hear the cries of the captive Pokémon from behind, which he's all the more driven to slam down the door a couple more times.]

Darn, it won't budge! [BANG BANG BANG] C'mon open up!

[If you got something else in mind, hit me up here or PM me! You're free to go ahead and come up with a starter too.]
