Remembrance of Courage Past
One day as Courage is digging in the yard, he discovers an overdue library book Courage was supposed to return two years ago, The Pixie and the Prickle Pirate. Muriel sends him to the library where the old and stern Librarian takes the book, and Courage is left with a fee of about $3,000. Courage is unable to pay, infuriating the librarian. As he leaves, the librarian places a curse over the book. Courage arrives back at the Bagge Farmhouse where he discovers the book sitting on the front porch. He shows the book to Eustace and Muriel and they both get paper cuts. And now the curse begins to take action, turning Eustace into the Prickle Pirate and Muriel into the Pixie. Eustace begins chasing Muriel with a giant club and Courage knows he has to pay that fee. Muriel runs from the farm followed by Eustace. Courage goes after his owners and chases them to the town, where on-goers look on in amazement as Eustace tries to shoot cannonballs at Muriel, who is standing on the rooftops. Courage tries to get help from Dr. Vindaloo, and after an ordeal with an ice cream cart, Dr. Vindaloo explains "There is nothing he can do about it. Nothing at all." Muriel and Eustace begin battling atop a billboard and Courage races to the library to fix the curse before Muriel and Eustace injure themselves. And to Courage's horror, the book fee is rapidly increasing. But Courage gains an idea to sell tickets for $100 to let the townspeople watch the Pixie and the Pirate fight. He acquires the money and pays the fee and the curse is lifted.
