User blog comment:ThePK/ThePK's Peek Inside the Wikia Offices/@comment-26190038-20150718202922/@comment-26573805-20150720213638

He changed his username because it relates to his name in real life too much, I also remember him from the Wander Over Yonder Wiki. His new username stands for The Pine Kip. Also, in my opinion, Pikachu is cuter than Mudkip.
