Tigre Hijo, also known as Tiny or Tora-chan, is a baby tiger separated from his mother and the circus. He enters Mimiko and the pandas' home, consuming Panny's food in a Goldilocks-like incident. His playful and curious nature drives him to explore alone, leading to brief separations from both the pandas and circus handlers. This independence unintentionally draws Panny to the circus grounds, initiating a comedic chase with performers.

During the pursuit, Tigre Hijo's actions cause Panny to collide with the tiger cage housing his mother. The reunion occurs when Mimiko and the tigress exchange the young animals—Tigre Hijo returns to his mother while Mimiko retrieves Panny. This interaction sparks an immediate bond between Mimiko and the tigress. Later, amid a flood, Tigre Hijo sends a bottled distress signal alerting Mimiko and the pandas to his entrapment aboard a stranded circus train with other animals.

After rescue, Tigre Hijo's playful antics with Panny accidentally activate the train, derailing it and nearly causing a crash. His narrative concludes peacefully as he attends the circus performance as an audience member alongside Mimiko and the pandas.
