The second varient is a large spider that hangs down from the celing. They will spin from their armored front to thier underside. Link will be damaged if he is cuaght in their spin. Thier are multiple methods to defeating them. In you child form here are two methhoods to defeat them. In the first you half to wait for them to spin to their back side and rush in and swing your sword before they spin, this is a risky methhood however. The best way to defeat them in your child form is to wait for them to spin to their underside and shoot them with your slingshot. In your adult form you have more powerful wepeans so you can shot them with you bow our hookshotand kill them even if they are facing you with there front.

Skulltula appear very much like their Twilight Princess predecessors. They are spider-like creatures with eight legs whos main attack is to dash its body towards Link. Skulltulas will appear in several different ways. Some just drop down the cieling, 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 utilizing the beetle.
Once a skulltula is on the ground, use your sword techniques to harm it. Once you've sliced it with a sword attack the skulltula will stand on its back legs, revealing its weak spot. 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.
