[Ah... That's a theory, now isn't it? Blue hums in thought... None of them really know how they got here, and it's the same for all the creatures here, probably, right? Blue is certain any Pokémon would become aggravated by certainly being dropped out of their natural environment.]

It might be.... Gyarados, their evolution, is renowned for its temper. So it's not the first time something like this has happened, but the last time it was-- well, unnatural. I guess this isn't very natural either, is it?

[Ah... explaining Pokémon evolution, huh? Blue thinks for a moment on how to explain it.] Pokémon change form when they get stronger, [He begins slowly] Kinda like how humans grow up, Pokémon grow up, too. Pokémon's bodies contain a lot of energy, so when that energy builds up enough, it triggers something in their cellular structure that causes a more rapid and sudden change of form. We call that 'evolution'.

[It's a lot of info to process, so he tries to pare it down as best he can.]

My gramps is a researcher of these kinds of phenomena, but there's still a lot we don't know about exactly why and how Pokémon evolve, besides observed conditions. And for the most part, the common factor is battling to get stronger. These Magikarp are really aggressive, but they're not a species known for being strong in battle....
