and at last I see the light

[The view clicks on to a view of an open window. Surprisingly, it's the first sunny day in days.]

Alright, come on.

[The feed pans to a Cherrim in overcast form, who bounces towards the open window, and immediately changes itself to its sunny form. It bounces happily on the window, flailing its arms.]

Cher! Cherrim!

You're happy, right? This is a nice day. It's a happy day for me too.

[There's a pause as the feed just shows the sunny view of Goldenrod, Namine sounding thoughtful above the happy chants of "Cher cherrim!"]

I've been here for a year now.

[She's quiet for a few moments, until an Altaria flaps near the window. Namine's arm holds out so she can pet the fluffy bird.]

Go stretch your wings some more while it's still sunny.

[It does and with a sigh, Namine pans the view to the still happy Cherrim.]

Are there other pokemon like this? That changes their form with the weather?
