Although things are scarce on Death Mountain, there are several items Link can get in Kakariko Village, most notably from the eerie House of Skulltula.
The Chicken Lady
Kakariko’s resident poultry expert seems to have lost all of her Cuccos. If Link helps her round up all seven of them, she’ll be sure to reward him for his efforts.
House of Skulltula
Shrouded in webs, the mysterious House of Skulltula is inhabited by a mysterious family that has been cursed for their greed. Once the richest family in Hyrule, their lust for Rupees was their downfall. If Link helps them break the curse, they will happily reward him with many presents.
