In Scarface, when Tony goes into the drug deal that turns bad, the Colombian dealers are called Hector and Martha. But in the original script, they are “The Toad” and “The Lizard,” while their two young henchmen are described as “hungry little piranhas.” Oliver Stone gave them animal names to suggest the kind of world Tony is stepping into — the animalistic, predatory jungle of Miami’s drug trade. And it’s why Tony calls Hector “frog face.”
If you pay attention, many of the characters throughout the film are referred to as animals for this very reason. The Bolivian drug lord Alejandro Sosa is a “snake,” Omar Suarez is referred to as “El Mono,” meaning “the Monkey” (“monkey ass!”), Elvira is referred to by Tony as “a tiger” (“a lady tiger!”), and Tony Montana is, of course, the apex predator — that’s why he refers to all of his rivals as “cockroaches.”
