Spider Jockey

Herobrine
 Spider Jockies are skeletons mounted on spiders, so they are the "horsemen" of the undead army. When they are killed, they split up into a skeleton and a spider. In Minecraft Tower Defense 1, spider jockies appear every ten levels. Spider jockies first appear in Tower Defense 2 in the village, where they are described to have "the speed of a spider and the health of a ghast".



Strategies
Spider Jockies are best defeated, as recommended in Tower Defense 1, with a fire charge dispensor at the end of a straight path, with lava two blocks before. Because spiders burn in lava, a strip of straight path with fully upgraded snowball dispensors and lava are also very effective.
