Meanwhile, Felldrake empowers Sheldgoose to hinder their progress while he gains strength.

Despite their efforts, the Caballeros struggle against Felldrake's might. In a critical moment, they receive help from Blazebeak, an ancient wizard, and together they strive to banish Felldrake. However, Sheldgoose accidentally destroys the staff, restoring order. Exposed, Sheldgoose is ousted from his position, and Donald becomes the new Acting President.
