Hey, I'm a total NoOB, I know....I know I'll get flamed for not knowing the name of the centaur type of guy who's half bull and half human.
Anyways, I found him in earthrealm and he gave me a 1000 red koins if I remember correctly.
I beat the game in Konquest then I was in earthrealm at that one place where the kid tells you to scare his grandpa. I had done it once before awhile ago and he paid me some koins and says if I do it again, he'd pay me more. I didn't do it though.
Anyways, I went back to that place, I talked to the kid and he said something like, "You got him good, blah blah"
Then I snuck up behind the grandpa really close and scared him so bad that it actually killed him then I talked to the kid again and he said "Murderer!" so I knocked him out. Then the centaur guy appeared to the left by the trees and I went and talked to him and then he disappeared. I don't know if it was just the right time of day, or if it had to do with the grandpa and kid, or what. Anybody else seen this or know more details about this secret. Just thought I'd post this info since I haven't seen any other posts about it.
