Gold Skulltula

Gold Skulltulas (黄金のスタルチュラ, Ougon no Sutaruchura) are special gold-backed spiders related to Skulltulas. They can be found in both Ocarina of Time and Majora's Mask.

Ocarina of Time
In Ocarina of Time when these creatures are destroyed, they leave tokens which are part of a curse placed on a man and his five sons who live inside the House of Skulltula in Kakariko Village. Over the course of the game, Link must collect tokens from the 100 Gold Skulltulas in Hyrule, freeing each family member from the curse one by one by collecting a certain number, and will receive rewards from each one, such as Pieces of Heart and larger wallets.

Gold Skulltalas can be located by listening for their distinctive scraping sound. They can be found anywhere, from fields to dungeons, although they will only appear above ground during the night. Skulltulas like soft soil, and can be drawn out by baiting them with small bugs. Some Gold Skulltulas, at least early on in the adventure, can simply be walked up to and killed, the token achieved just by walking up to it, but Skulltulas later in the game might require ranged weapons to kill, and the Boomerang or Hookshot needed to retrieve the tokens.

In order to make finding them easier, a small Gold Skulltula icon will appear next to an area's name on the map once all the Gold Skulltulas in that area have been collected.

Majora's Mask
In Majora's Mask, there are two Skulltula Houses (the Swamp Spider House and Oceanside Spider House) which contain 30 Gold Skulltulas each. Rather than collecting tokens from slain Gold Skulltulas, the spiders dropped Gold Skulltula Spirits. If all 30 spirits are collected within the three-day cycle, a reward will be waiting for Link.

Glitch
In Ocarina of Time, at Hyrule Castle, near where the drain entrance is to the inner courtyard, there is a secret hole near a tree that can be opened with the Song of Storms. In this hole, a Golden Skulltulla could be found. By killing it, boomeranging the resulting token and stepping into the light as soon as the boomerang picks up the token (before you grab it), a glitch will occur where the token will be collected, but the Skulltulla will not register as destroyed, and respawn every time this is done. With this, it is possible to collect more than 100 Gold Skulltula tokens. The glitch remains present in the Collector's Edition.
