Grandma Sparkle

Grandma Sparkle is an old woman who resides at Wilhelm's Wharf. She is just a merchant but has a very limited inventory of items to sell and even more limited caps. The door to her shack is subtitled in red, but you it doesn't look like you lose karma when you enter. Her shack can be looted for some weapons such as a Hunting Rifle and a supply of ammo.

Grandma Sparkle is armed with a Hunting Rifle and Brahmin-Skin Outfit. However, she is extremely weak and dies after only a few shots from even a low-level pistol. Despite being armed, she always seems to run from combat. If wandering Raiders or monsters approach Wilheim's Wharf, she'll usually retreat into the safety of her shack. If attacked by the player character, she has a tendency to run off in random directions (often right into the river itself).
