Okay, so I was in the middle of running a experiment on the servers and decided to try it on utopia because I missed the cliff in SMP6 and fell to my death and was knocked off a cliff into lava by a ghast on SMP9.. I am using ender pearls to travel as far out into the nether as I can and portal back to see how far from spawn I become.. I am now taking a break in a netherwart chamber and I keep hearing the zombie pigmen crater themselves, and cant help but think "Are the zombie pigmen a cousin to the lemmings..?" I mean they are falling at regular intervals.. xD
