Scrooge decides to take Louie to his Money Bin to show him the value of a hard day’s work after witnessing his laziness. While there, Louie loses Scrooge’s Number One Dime and decides to use Gyro Gearloose’s robotic light-bulb, Little Bulb, to get it back. However, he causes it to become a giant coin-collecting robot, and is forced to stop it all on his own and retrieve the Dime before Scrooge notices. Meanwhile, Dewey and Webby face the McDuck Archives’ dedicated keeper, Mrs. Quackfaster, in order to gain information on Della and solve the mystery of her disappearance. Eventually, they find a note from Della saying “Scrooge, I took The Spear of Selene, I’m sorry” and decide to keep this a secret until they know more.
