Senor El Dik Dak is a small boy of nebulous origin befriended in South America by the powerful El Bruto. Carlos, who was aide de camp to El Bruto before the boy's arrival resents his younger rival. In defending the best interests of his benefactors, El Dik Dak makes a friend of a jaguar. And by saying only the word ""Ummm"" and nothing more he outwits the bad men and brings happiness to the populace of a strange city, Keura, whose inhabitants wandered into the jungle from Peru. Before that, methinks, the Keurans emigrated from the comic books. (Arana, high princess of Keura, is guarded by ocelots, etc.) Violent and sensational for this gringo's tastes.
