Baron Von Sheldgoose

"You don't know who you're messing with! I am Baron Von Sheldgoose, President of the New Quackmore institute! And I'll be watching you, very closely, Donald Duck! Microscopically close! Sub-atomically close! Eye constantly close! One slip up, and I vow, on my great ancestors, to tear your little shack to the ground! Good day!"

History
In "Dope-a Cabana", when Donald Duck travels to New Quackmore to acquire his great-grandfather Clinton Coot's inheritance he mistakenly arrives at Sheldgoose's mansion and begins making a mess. Sheldgoose sees this occur and is totally outraged, telling Donald his house is at 122 and one eighth Sheldgoose Square, not 122, before getting his bodyguards to roughly kick him out. Later on, Sheldgoose is enraged to find that Donald, José Carioca, and Panchito are having a yard sale, and rushes down to confront the three for breaking New Quackmore customs. However, upon noticing a ring bearing his emblem, he realizes that the items they are selling are Clinton Coot's magical relics and decides to take advantage of his discovery by offering to buy the artifacts along with the entire estate for a million dollars, provided that they possess a particular book. Enthralled by the money, Donald, José and Panchito search for and discover the book, however, upon opening it, they are faced with Xandra, the Goddess of Adventure.

In "Labyrinth and Repeat", Sheldgoose is still waiting for the book to be handed to him, while the trio deal with Xandra, who ultimately explains the story of the original Three Caballeros and how they went on great adventures together, before taking them to Crete to face the Minotaur. Meanwhile, Sheldgoose is tricked into buying the ring he had noticed for a thousand dollars by April, May and June, and he begrudgingly tells himself it doesn't matter so long as he gets the book. After Donald, José, Panchito, now having taken up the mantle of the Three Caballeros, and Xandra return, Donald refuses to sell the estate to Sheldgoose, infuriating him. Upon starting to walk back to his mansion, he finds himself dragged along by his ring, which leads him to discover Lord Felldrake, still trapped within his staff, beneath his mansion. Sheldgoose grabs Felldrake's staff and gain's the latter's magical powers, who also decides to summon an "old friend".
