The Heartland Theme Park is the amusement park from Heartland, whose director is Mr. Heartland. It is a very popular park in the Yu-Gi-Oh ZEXAL manga, and contains many attractions that attract people from many different places. Because of that, Dr. Faker "provided" 3 Numbers Hunters to hunt "Numbers" secretly inside the park, disguised as employees. They are Captain Corn, Thunder Spark and Cologne, who got known as the "mascots of the park". Mr. Heartland also allowed Duelists to enter the park for free, to make the hunt for "Numbers" easier.
