Baron Von Sheldgoose is the wealthy president of the New Quackmore Institute and takes great pride in his wealth and status and maintaining a certain decorum. When Donald Duck arrives to claim his great-grandfather's inheritance, he mistakenly arrives at Sheldgoose's mansion and immediately gets on his bad side. When Sheldgoose sees the Caballeros trying to hold a yard sale of all the artifacts within the cabana, he is initially furious, but sees an opportunity to claim some of the magical items that Clinton Coot held and offers to buy the whole thing for a million dollars. In the end, they reject his offer, but not before he bought a ring belonging to his ancestor: the dark sorcerer Felldrake Sheldgoose. The ring opens a secret room in his mansion holding Felldrake's magic staff that he was imprisoned in, who offers to share his dark powers with his descendant.
- Von Sheldgoose physically resembles Gladstone Gander's father Goosetave Gander.
