Sunny Smiles

 is a local ranger living in the Mojave Wasteland in the town of Goodsprings in 2281. She is often tasked with killing bothersome Geckos harassing the water wells.

Background
She owns a dog named Cheyenne who sticks with her all the time.

Quests

 * Back in the Saddle: Sunny Smiles gives the Courier a varmint rifle and helps teach the Courier how to survive better in the Mojave Wasteland while the Courier can assist her in taking out Geckos.
 * By A Campfire On The Trail: Sunny shows the Courier how to make items on campfires, a Healing powder in this quest.
 * Ghost Town Firefight: She can help the Courier defeat the Powder Gangers.

Other interactions
It is possible for Cheyenne to die during the tutorial quest, in which case Sunny's dialogue will change slightly to show her remorse. It does not, however, have any real impact on the completion of the quest.

She also gives the player bobby pins, and a copy of Locksmith's Reader if the Courier asks her about work.

It is also possible for her to die when fighting the Geckos when you're on the quest with her, especially if you leave her alone during the fight with the Geckos. This also seems to prevent saving the town in "Ghost Town Gunfight".

Notable quotes

 * (To Cheyenne) "Cheyenne stay (To Courier) Don't worry, she won't bite, unless I tell her to."

Bugs
During the tutorial it is possible that skipping through her dialog options will skip ahead in the quest, possibly completing it early and missing some of the rewards. The author is unsure if this glitch could break the quest completely. (For example, after killing the geckos I was skipping through her dialog quickly and when I got to a dialog option, she began speaking as if the player was further in the conversation. After I followed her to the campfire, she congratulated me for making a healing powder and the quest was automatically complete.)
 * I can confirm that this happened to me, however the reason for this i believe is the presence of healing powder in your inventory. Having healing powder in your inventory when this quest is triggered at the camp fire automatically completes the quest.
