Synopsis
Donald arrives in time to join Xandra and the Caballeros and the four of them charge the basement of the mansion, while Felldrake gives Sheldgoose powers of his own to stall them while he reaches his full power. Sheldgoose's attempts to summon evil allies from their past adventures are countered by the Caballeros's own allies, and they arrive in time for Felldrake to awaken and destroy the Institute. The Caballeros try to fight Felldrake but are overpowered and pushed to the verge of defeat. In their last moment, they are contacted by Blazebeak, an ancient wizard whose power had been protecting them through their amulets. With his power, the Caballeros attempt to banish Felldrake back into his staff, but Sheldgoose destroys it out of panic and inadvertently restores everything to normal. His true nature exposed, the boardmembers strip Sheldgoose of his presidency and Donald is named the new Acting President to everybody's happiness. As Sheldgoose escapes on Leopold, he finds that Felldrake is now trapped inside his own body, and Felldrake decides to call in a favor from an "old friend"
