In the comic The Riddle of the Rusty Scupper, April and the Turtles are vacationing in the Caribbean, when they encounter a pirate ship called the Rusty Scupper. Checking it out for treasure, they find a note reading "Lift the curse by solving the riddle." A Skeleton Pirate captain on board the Scupper then tells them the riddle:
"What's black and white and red all over?"
The skeleton pirates then attack the Turtles and April, who make a few guesses as to the riddle's answer. April deduces that it must be something pirate-related, and it dawns on her when she sees it: the ship's Jolly Roger against the sunset. The captain thanks April and the ship disappears.
