Several varieties of skulls possess legs made out of bones who crawl about the place. These include Skull Crabs from Castlevania: Rondo of Blood, Spittle Bones from Castlevania: Symphony of the Night, and Skull Spiders from Castlevania: Order of Ecclesia.
Game specific information
Skull Spiders appear in various areas of Castlevania: Order of Ecclesia. One appears in the sunken ship area of the Kalidus Channel, and many more appear in Tymeo Mountains. Touching them will poison you, but fortunately they move very slow, allowing you to defeat them easily. However, in Hard Mode they move very fast (as fast as Shanoa wearing the Winged Boots), making them very hard to kill. They drop a rather uncommon glyph: the Fidelis Aranea, which allows you to summon a Skull Spider to fight for you, which can crawl on walls and ceilings, and also poisons any enemy which comes in contact with it (unless it passes a poison resistance check). The Skull Spider will move faster as you level up the glyph.
The Skull Spider appears in this game, but this time as an accessory that can be equipped on the wrist. It can only be unlocked by linking the Wii to your Nintendo DS if it already has Order of Ecclesia in it via Wi-Fi.
