Tameable Spiders

A Tameable Spider would be a great addition to the Minecraft world of tameable mobs, as this mob, when tamed, would allow you to climb up great distances, as we all know horses are terrible at climbing. The mob would also be able to jump fair distances, and will attack any mob that attacks you, except its own brethren. The taming process involves you having to gain its attention at night, then trapping it in a room (the room is simply to contain it until the process is over), and hitting it with a wooden sword, enchanted with Bane of Arthropods, level 1. Then you will have to drop two spider eyes, and lure a passive mob, such as a chicken to fulfill the deal. Then you can saddle it, and explore the Overworld like never before. To keep it tamed, you'll need to 'sacrifice' a passive mob every day, otherwise it'll turn hostile on you, and summon two skeleton horsemen, to boot. This idea has circulated, I believe, a few times, but I'm pretty sure this version hasn't sprung up. I hope you enjoy this idea, and if you do, please vote for it.
