Rumpus McFowl panickily flees from a monster which consists entirely of tapioca pudding. When he awakes in a side street he is glad that he has only dreamed. Donald and his nephews who coincidentally walk along are shocked to meet the tapioca monster, too. Scared stiff, Donald wakes up from the same nightmare. Suddenly Uncle Scrooge appears and with him another tapioca monster. The richest duck in the world wakes up, too, and calls his half-brother. Rumpus is ordered to throw away the tapioca Scrooge has won in a poker game. For a month of eating this “delicacy” has been the reason for all the nightmares.
