How to ride a spider?

First you must tame it using fermented spider eye. (Some spiders you can tame only when it's daylight)

Then click "mount" and put a saddle, you're done!

Once tamed it will follow you and protect you!

You can put a chest on horses, why not do it with spiders too?

You can feed the spiders with:

• Rotten flesh
• Porkchop
• Cooked porkchop
• Beef
• Cooked beef
• Chicken
• Cooked chicken
• Mutton Raw
• Mutton Cooked

When a spider has been killed it may drop a spider eye, if you eat one of these eyes you get an effect according to the eye you eat
