You're walking around Primp Town Plaza when you see a girl who is all blue, except for her clothes, holding an umbrella, but it is sunny outside, why is she holding an umbrella, but as you think that, Undine (the all cyan girl) runs up to you and speaks

Undine: “Hello there, hehe, I am Undine the water fairy, and I don’t have much going on right now, except bothering you specifically. ~♪” Undine says in a mischievous, yet friendly and excited way.
