A Sea Festival Mystery

Dawn, Lucas, and Barry were enjoying the festivities at the beach.

That festival was so fun!

I know, right?

But I still feel like I need more!

You sure are full of energy, Barry.

Come to think of it, I remember hearing the festival would have a Pokémon battling event.

But that hasn't happened yet today, has it?

Oh! That's true! I was looking forward to that.

But the sun's already setting. Isn't the festival about to, y'know, end?

Mwehehe!

You did well to stay this late!

And you are...?

Wait... These are the lifeguards from the beach today!

Indeed we are!

But in truth, we're also your opponents for today's secret festival event...

"Brave Heroes of the Sea"!

If you can take us down one by one in Pokémon battles, we'll recognize you as exactly that, brave heroes of the sea!

And that's not all, we'll tell you a little secret, too!

I don't really get what's going on, but we've just gotta beat you guys, right?

Dawn! Lucas! Let's take 'em on!

Of course! I'm fired up!

Heheh... You're a confident bunch!

But our Pokémon work as lifeguards day and night. They're strong too, you know!

Hm?

I feel like I've seen that same combination of Pokémon somewhere recently...
