Skulltula are spider-like creatures that have appeared in many Legend of Zelda games.
Ocarina of Time
The first variant is a small, white spider that crawls on vines. They can be taken out with the sword, but most of the time they will be beyond your sword's reach. The best way for Link to defeat them is with a ranged weapon, such as the Slingshot or Bow and Arrow. Should Link try to climb on the vine without killing the Skulltula first, the Skulltula will see him and charge, causing Link to fall back to the ground.
The second variant is a large spider that hangs down from the ceiling. They will spin from their armored front to their exposed underside, causing Link damage if he is caught in the spin. There are multiple methods of defeating the Skulltula; while Young Link, there are two methods primarily used. The first is to wait for them to reveal their back side and rush in with a sword attack. A second, more effective way is to wait for them to expose their underside and shoot them with a slingshot. As an Adult, Link has more powerful weapons, so he can shoot them with the Bow or Hookshot while facing their armored side.

The third variant is the Gold Skulltula. There is an entire side quest dedicated to them where you hunt down the Gold Skulltulas to free the cursed family that lives in the House of Skulltula in Kakariko Village. When Link kills a Gold Skulltula, he will get a token. When Link gets a certain amount of tokens, (10, 20, 30, 40, 50, and 100 tokens) he will be awarded with different prizes.
In Majora's Mask, Skulltullas have the ability to perform a spin attack which can damage Link. They don't take damage when struck from the front side by the Hookshot like Ocarina of Time, but the Hero's Bow is still effective in eliminating them. There is also a sidequest in Majora's Mask which is centered around Link finding and killing Skulltulas in different Skulltula houses across Termina. There are only two Skulltula Houses, located in the Southern Swamp, and one located in Great Bay Coast. The prizes for them are as follows: The Mask of Truth is found in the Swamp house, and the The Giants Wallet ( only found on the first day) and Heart Piece #34( found on the 2nd and 3rd days) are found in the Great Bay Skulltula House.
Skulltula's have similar properties to their ancestors of Ocarina Of Time and Majora's Mask in this game, with a shielded front side, and vulnerable back side. However, they will walk around on their own after being targeted or touched. Afterwards, they'll charge at Link until close enough to strike. If struck directly, Skulltulas will typically deflect the attack, giving off a blue spark on contact; although, if attacked at the right time, will give a red spark, signifying a successful hit. Strategies on this enemy include: rolling around and attacking the back side, deflecting a bite attack and striking, or thrusting while they charge up an attack. Using a boomerang can be effective, as it momentarily stuns the Skulltula. These enemies can be found in the Forest Temple, as well as in various locations across Hyrule Field, specifically cavernous areas.
Skulltula appear very much like their Twilight Princess predecessors. They are spider-like creatures with eight legs whose main attack is to dash its body towards Link. Skulltulas will appear in several different ways. Some drop down from the ceiling, others are hanging from a string, while some have full blown spider webs created to block your path. Link can knock down skulltulas by breaking the string or spider web by utilizing the Beetle.
Once a skulltula is on the ground, Link can use his sword techniques to harm it. Once Link has sliced it with a sword attack the skulltula will stand on its back legs, revealing its weak spot. Link can then slash at the large purple jewel on its stomach to defeat the skulltula. In some cases, after hitting the skulltula a number of times, it will flip over and land on its back. At this point Link can jump and deliver a finishing blow, stabbing right through its weak point.
• In Ocarina of Time and Majora's Mask, Skulltula is one of the few enemies that can be invisible to the naked eye. Link can use the Lens of Truth to make them visible.
