That's true! If Karpje does evolve, she'll be big enough to carry all of us on her back, even if Hina and Mecchan both evolve too! How amazing would that be?

[The Magikarp splashes some more in excitement, and Frieda dotes on it.]

Don't get too excited! Take your time deciding. - I should find some more friends for her while she's still small and approachable.

[Granted, "small" is relative (and so is "approachable"... but compared to a Gyarados, most pokémon are.]
