the laboratory, Dr. Zabor realizes that the serum's effect was only temporary and Ramona has turned back into a chimp. Meanwhile, Duke is on his way to see Pepe Bordo, but is ambushed by Chula who carries him to the laboratory where Dr. Zabor tells Nona that the day's work is done and that she should take Sammy to the village and after they leave, injects Duke with the serum and watches him turn into a gorilla. As Nona and Sammy return to the laboratory in search of Duke, Dr. Zabor explains that the gorilla is actually Ramona advanced to a higher level of evolution.

Dr. Zabor is the manager who advises him, "You'd better get some laughs this time or you'll be collecting unemployment insurance". Finally, Saloma, a dancer in a Polynesian act, embraces Sammy, gives him a big kiss and, this time, he likes it as he and Duke perform their act with another
