NEVER use a white, rainbow-emitting Yoylelite ever again.
After TPOT 21, Marker got eliminated but decided he would hang out with Stapy, since he was the only one who played Toss the Dirt with him. They both use that gray Yoylelite with the rainbow to travel to Marker's dimension, where he's on the Pedestal of Awesome and with his 300 and something siblings.
Though things take an interesting turn when the markers begin to vanish. And it is none other than Dark Markery, who is after Marker for a reason he does not know. At least... he believes he doesn't know. Dark Markery kidnaps Marker and gives Stapy 24 hours to find all the markers... before his best friend becomes an ink splatter.
