There are four Gold Skulltulas in the Inside the Deku Tree dungeon, 3 of which you can get on your first visit. The last one cannot be gotten until you have acquired the Bombs and Boomerang.
#1) This Gold Skulltula is in the same room as the chest with the Compass. Stand on the button to raise the platforms and instead of going straight across, go into the little alcove on the left, where you'll find the Gold Skulltula.
#2) Once you jump and break through the web in the first room, you'll drop into the room below with some water. This Gold Skulltula is on the vines that lead back up to the first room.
#3) This Gold Skulltula is in the same room as the one above. There is a grating near the step switch, and you'll find it on that grating. Kill it with the Fairy Slingshot, then jump off the platform to grab the token.
#4) You will need the Bombs and the Boomerang for this Gold Skulltula, so come back after finishing the dungeon inside Jabu Jabu's Belly. Once you do, head back to the room where you encountered the Gohma Larvae that fall from the ceiling. In one of the corners is a web, so use a Deku Stick to torch it. Kill the Deku Baba and bomb the wall behind it to make a door appear. Go through and use your Boomerang to kill and collect the token from the Gold Skulltula.
