Marker is a purple washable marker. He likes to write messages on his arms such as "IMMUNITY GOES TO ME!" Marker is good-natured and cheerful. He also loves to play games! His favorite is Toss the Dirt, but he's willing to play plenty of other games with his friends Foldy and Stapy. He's not so good at Rock-Paper-Scissors, though, because he keeps getting his fingers twisted into house-shapes. And 4-shapes. And hecatonicosahedroid-shapes.
