I saw three in one minecraft night. It was in January when I had only been playing for around a week so I thought that this meant that spiders were rideable. Lol, I lost about 10 lives trying to figure out how to ride them.
I was killed both times. First one because I was taking some pigs to an underground ranch with no armor, and then I was caught by surprise. Second one because, again with no armor, I was exploring a forest at night and a jockey with 3 other spiders got me. I only had a stone sword and so I died.
Both were the best moments I had in MC, except for my first slime.
I've seen. OVER 9000! jk I've seen about 6 in a year
._. I was going to make that reference...damn you. XD Jk, but I was going to say that XD
I've only actually seen 1 in my minecraft playing lifetime, I was like this (I was a noob back then) "Oh hey look its one of those spider skellington thingys, wdf? Ima go punch it to death >:biggrin.gif: *dies* ****!"
