Fallenchicken is an '08er. He was lost in the Purge and now resides in Selkath. He created an alt called chickenrising, but that was before the Deletion.
In fact it is so enormous he once poked Salo in the eye with it due to an accidental erection caused by a large blue elephant bending over infront of him. However it is unknown why Salo was so close to Fallenchicken's penis in the first place.
(NB: We all know why really, it's because Salo was hungry for some hungarian sausage)
