Articuno, Moltres, and Zapdos have decided to tour the world rather than just stay in Kanto since Kanto wasn't all that interesting or fun to them anymore. The three would pass by Sinnoh, looking at the Alabaster Icelands as they flew before spotting something.

Articuno: Well, this is interesting.

Moltres: He'd sigh What'd you find, Articuno?

Articuno: She'd look at Moltres See for yourself.

Zapdos stayed silent, trying to find what Articuno saw, same with Moltres.
