Joakim (Farbror Joakim) #3/1986

In a quiet moment of cleaning, Kalle stumbles upon an old tale in Joakim’s library—*Sindbad Ankas äventyr*—a forgotten story of a daring hero who sets out to rescue Princess Caisa from the clutches of the fearsome Björnligan and the treacherous Fågel Rock. The legend unfolds like a whisper from the past, blending adventure and mystery in a world where courage is measured in bold deeds and hidden paths.

In "Mystiskt försvinnande," Professor Geo Foss vantror sig efter att ha hittat Wudus guldskatt, och blir snabbt tillfångatagen av de mäktiga tjuvarna Slim och Slum. När en okänd tjuv försöker utnyttja situationen genom att utge sig för att vara Foss' son, får Musse och Långben en ny, farlig uppdrag att följa – men det är svårt att veta vem man kan lita på.

In "Tunnelkungen," the well-meaning but clumsy grizzly bear Mullebjörn accidentally digs a tunnel into the wrong place—intending to reach Joakim’s treasure chamber, he instead tunnels straight into a prison. With his oversized digger and a heart full of hope, Mullebjörn stumbles into a world far from the treasure he sought.

In "Indianskatten," Joakim stumbles upon a map leading to the lost treasure of the Ombac tribe. Though the site reveals only an ancient stone tablet with mysterious carvings—dismissed by Joakim as worthless—the tablet's discovery earns Knattarna a hefty reward when they take it to the museum.
