What did John Hammond do to fool people and what animal did he use In the book Jurassic Park?

In Michael Crichton's "Jurassic Park," John Hammond uses a clever marketing strategy to fool people into believing his dinosaur theme park is safe and entertaining. He manipulates public perception by showcasing a seemingly harmless baby Velociraptor, showcasing its appeal and innocence to distract from the inherent dangers of the adult dinosaurs. This tactic helps him garner support and investment for the park, despite the underlying risks involved.
