Murky Dismal's real first name is revealed to be Murkwell.
Murky Dismal's hatred of colors is revealed in a flashback to when he was a baby. His mother catches him coloring on the walls (crayons, paint roller, and an airbrush). She yells at him, "You're going to get rid of every bit of that color if it takes you all day... if it takes you the rest of your life!"
