DuckTales is a platform game developed and published by Capcom and based on the Disney animated TV series of the same name. It was first released in North America for the Nintendo Entertainment System in 1989 and was later ported to the Game Boy in 1990. The story involves Scrooge McDuck traveling around the globe collecting treasure and outwitting his rival Flintheart Glomgold to become the world's richest duck. Produced by key personnel from the Mega Man series, DuckTales would go on to sell over a million copies worldwide on each system, becoming Capcom's best-selling title for both platforms. The game was praised for its tight control, unique and non-linear gameplay and bright presentation, and is often regarded as one of the best titles for the NES, appearing on numerous "Best of" lists.

The Beagle Boys attempt another raid on Scrooge's money bin, with Baggy, Burger and Bouncer Beagle capturing Huey, Dewey and Louie. After Scrooge rescues them, he finds Big Time Beagle in his office with a painting in his hands. With the help of Duckworth, Big Time is defeated and retreats. The painting reveals the locations of five treasures, and Scrooge wastes no time to set out for them. Scrooge and Launchpad visit the Amazon to find the Sceptre of the Incan King. Using eight golden coins, they uncover the hidden temple of Manco Capquack, but the sceptre is lost and the temple is destroyed by its guardian statue. The chief of the natives then approaches Scrooge and Launchpad and thanks them for returning their city to them, and gives Scrooge the recovered sceptre in return, which was just the king's back scratcher. Scrooge, the nephews and Webby visit the castle of Drake Von Vladstone, also known as Dracula Duck, who was the heir to the Coin of the Lost Realm. The boys fall into a trap door and are spread throughout the Transylvanian mansion, but Scrooge saves them from the Beagle Boys, disguised as ghosts. Each of the beagle boys were also carrying a torn sheet of paper which contained part of a riddle. They uncover a mirror where Scrooge solves the riddle, and Magica De Spell reveals herself, who is also after the coin. Scrooge and Magica then face off for it, and the sorceress is defeated and retreats empty-handed. Scrooge and the nephews travel to the African Mines to find the Giant Diamond of the Inner Earth, but they find the workers are being scared off by voices and earthquakes, claiming the mine is haunted. Deep underground, Scrooge discovers that the Terra-Firmians and their games are the cause, and after interfering he is attacked by their king. Defeated, the king makes an agreement with Scrooge to stop the games in exchange for the mining operations to continue, as it will rid them of the diamonds they consider to be "garbage rocks". He gives Scrooge the Giant Diamond of the Inner Earth to start with.
