He first appears during the song "Two Worlds" and the beginning of the film, where he is seen crawling from his mother and onto Kerchak's arms. The baby gorilla almost falls out of the nest, but his father stops him. He is then seen playing with his father by climbing up his back and sliding off. He then runs to his mother Kala and she rubs her nose with his and then tosses him into the air.
One night, as Kala and Kerchak sleep, the baby gorilla notices a frog hopping by and wanders away from his parents, chasing the frog deep into the jungle, unaware that the ferocious leopard, Sabor, is out hunting. When Sabor spots the baby, she begins chasing him; the baby gorilla tries to race back to his parents, but Sabor corners him.
Kerchak and Kala hear their son's cries as he is being eaten alive and race to try to protect him, but Kerchak realizes that they won't be able to save him, so they stop in their tracks. Kala cries sadly in Kerchak's arms at the loss of their only child.
Sometime after, as Kerchak moves the troop to another home, Kala hears another baby crying, leading her to a treehouse, where she finds a human baby boy whose parents were also killed by Sabor. Though Sabor is still inside the treehouse and gives chase, Kala manages to save the baby and escape Sabor. When Kala brings the baby back to her family and asks Kerchak if she can keep it, Kerchak tells Kala that the baby won't replace the one they lost but that she may keep him.
Kala then names the baby boy Tarzan. Even though Tarzan and Kala's biological son never meet, in a sense, they are technically adoptive brothers. His death, along with the deaths of Tarzan's Parents, are avenged by Tarzan when Sabor is finally killed.
- In the original novel, the character is the son of Kala and Tublat. He died when Kala tried to flee an attacking Kerchak. She carried his corpse with her, until she came across Tarzan. Taking in the human baby, she left the remains of her own child in Tarzan's crib.
