chickaber, aka Sebastian was one of the later players to join the server. He first met Sam and Patrick when he was on the same soccer team as them. They discovered he had Minecraft and invited him on the server. He has not always had the best of relations with matty12164 and has often fought with him.
It is known he built a bunch of stuff on the second creative map, but it is unknown exactly what. It is known that he built a jungle village in the trees where the currency was slimeballs, and the only two people who had homes there were Weltinator2 and Chickaber. (One of his minor additions compared to his other amazing things)
He is now one of the lead members of a Youtube group known as Team V.I.P.
