Help name my pony!

[Iodine]

This girl is based on bipolar/manic-depression and duality. She has hyper and sullen moods, and needs a name related to that! She will eventually show up in the Hayshire comic.

Maybe something to do with the sun and moon?

Sundowner

[the dark gods]

Moonbright.
Lunar-flare.
Bi-solar.

[Tiger]

[Anibell April Dash]

Yangin Yin ?

[sorikuXIII]

Twilt Dawn

[Gracie Sky]

Candid Eclipse

She needs the nickname "Crazy" Eclipse so she can say "Hi, I'm Crazy!"

Edit:

I'm revising my idea.
After giving it some thought, Candice Eclipse sounds far smoother, although Candice is a human name and I do not like giving ponies human names.
The other idea I had was to pun-ize the nick name and make it Craze Eclipse. You still have Crazy and Eclipse, but the two names are blended together.

Thanks for the suggestions, everypony! I'm still not set on her name, but I was thinking Sunshade.
