Smiley (Fallout 2)

Smiley is the trapper to see about... well, anything that involves the gecko. He claims he was raised on gecko milk. He is also the main squeeze of Klamath citizen Ardin Buckner who puts you on a quest to find Smiley in the first place. He can be found in the Toxic Caves, which he discovered in an attempt to locate the origins of the valuable golden gecko. If you get to the toxic caves soon enough, you might have a chance to save his dog from being killed from the geckos. After you have rescued Smiley, he will appear in The Buckner House in Klamath. Smiley will teach the Player the Gecko Skinning perk as a reward for saving his life. Other than that... well, he's just a source of gecko lore.
