Fanon
is a popular ship. However, compared to other ships, it's not quite as popular. For example, Blockwood (Blocky/Woody) or Snowlight (Snowball x Lightning). They haven't interacted since season one, decreasing the popularity of. A main thing that rises the popularity though is the squad of Pen, Eraser, Blocky and Snowball. Many fans ship Penraser (Pen/Eraser), so they would also ship because of the four's friendship.
