Fanon
Markning sort of popular in the Battle for Dream Island fandom, but it's foreshadowed by it's rivalry ships, Snowlight (The ship between Snowball and Lightning) and Markapy (The ship between Marker and Stapy). The ship started in TPOT 1 when Marker asked Lightning if he wanted to be friends. The fandom liked how Lightning still wanted to be friends even after Marker rejecting in BFB 1.
