The character commonly identified with Oolong appears in the Taiwanese live-action film Dragon Ball: The Magic Begins under the name Piggy, since that production gives its heroes and villains different names from those used in the original Dragon Ball series. Piggy is an overweight man with the ability to change his shape, and this shapeshifting is the skill that defines him throughout the story. He enters the plot when the young protagonist Monkey Boy meets and defeats him in a brief fight; after this encounter, Piggy joins Monkey Boy and the traveling girl Seetoe in their search for the seven Dragon Pearls. His background ties him to the classic Chinese tale Journey to the West, as he claims to be a descendant of Zhu Wuneng, the pig companion of the Monkey King in that story, and this connection reinforces his place as a source of the film's comic tone and a less heroic member of the group. As the journey continues, his relationship with Monkey Boy deepens until the two come to treat each other as brothers. Piggy also has a personal stake in the central conflict, as he is eventually revealed to be the owner of one of the seven Dragon Pearls. This makes him one of the five pearl holders, along with Monkey Boy's household, the bandit Westwood, the martial arts master Turtle Man, and Seetoe, whose combined resistance is needed to stop the villain King Horn. King Horn, who already possesses two of the pearls, wants to gather all seven in order to conquer mankind and rule the universe, so Piggy's ownership of a pearl places him directly in the villain's path. Together with the other heroes, he takes part in the effort to defeat King Horn and his two warriors before their plan can succeed. While his contributions are tied mostly to his transformations and to the humorous side of the story, his status as a pearl owner and his friendship with Monkey Boy make him a genuine member of the hero group rather than a mere bystander.
