The Backyardigans meet Tarzan

The Backyardigans meet Tarzan is an upcoming Nick Jr./Disney crossover to be made by Hiatt Grey.

Plot
In the early 1860s, an English couple and their infant son escape from a shipwreck, and end up near an uncharted rainforest on the Congolese coast. The couple build themselves a treehouse from the ship's wreckage. Meanwhile, the leader of a group of gorillas, Kerchak, plays with his son until a leopard named Sabor kills him. Soon afterwards, Kerchak's mate Kalahears the infant son's cries and finds the treehouse, where she discovers that Sabor has killed the couple as well. Kala encounters Sabor, and escapes with the infant in her possession. Kala takes the infant back to her troop to raise as her own, an action which Kerchak objects to. Kala adopts the human child, naming him Tarzan.

When aged five, Tarzan begins to befriend other animals, including his adoptive cousin and Kala and Kerchak's niece Terk and a paranoid male African elephant named Tantor; but he is treated hostilely due to physical differences, so he makes great efforts to improve himself. As a young adult, Tarzan manages to slay Sabor with a spear he crafted, gaining Kerchak's respect.

The gorillas' peaceful life is interrupted by the arrival of a team of English explorers, consisting of Professor Porter, his daughter Jane, and their tour guide, a hunter named Clayton. The explorers are looking to study gorillas. Jane accidentally becomes separated from the group and is chased by a mandrill troop, with Tarzan saving her. Tarzan studies Jane and realizes she's similar to him. Jane leads Tarzan to their camp, where Porter and Clayton garner interest in him. Porter views Tarzan as an opportunity for scientific advancement, while Clayton desires to persuade Tarzan to lead him to the gorillas. Kerchak firmly warns Tarzan to stay away from them, but Tarzan disobeys his warnings and continues to return to the camp, where the Porters and Clayton teach him how to speak English as well as what the human world is like. As time passes, Tarzan and Jane gradually begin to fall in love. Because of Kerchak, Tarzan still refuses to lead the explorers to the gorillas.

The explorers' ship soon returns to retrieve them. Jane asks Tarzan to return with them to England, but Tarzan asks Jane to stay with him when Jane says that it is unlikely that they will ever return. Clayton convinces Tarzan that Jane will stay with him if he leads them to the gorillas. Tarzan agrees and leads the trio to the nesting grounds, while Terk and Tantor lure Kerchak away to prevent him from attacking the humans. Jane and her father are excited to mingle with the gorillas. Suddenly, Kerchak returns to see them and attempts to attack, but Tarzan holds him with chokehold, allowing the Porters and Clayton to escape. An enraged Kerchak accuses Tarzan of betraying the troop, causing Tarzan to run off in guilt. Kala takes Tarzan to the treehouse, where she shows him about his true past. In the end, Tarzan puts on a suit that once belonged to his father, signifying his decision to go to England, before he and Kala share a bittersweet goodbye.

When Tarzan boards the ship with Jane and Porter, they are all ambushed by Clayton and his traitorous band of stowaway thugs. Clayton reveals his plan on how he hopes and plans to seize the gorillas, and he was just using the Porters for a way to go to the jungle. He subsequently used Tarzan to find the nesting grounds and locks Tarzan, Jane, and Porter away to prevent them from interfering. Tarzan manages to escape with the support of Terk and Tantor and returns to the jungle to save the gorillas. During the battle, Clayton mortally shoots Kerchak in the chest. Tarzan fights Clayton across the treetops. Although Tarzan spares Clayton's life and destroys his shotgun, Clayton tries to kill him with his machete. Tarzan then traps Clayton with vines, but Clayton attempts to free himself and slashes all of the vines. In the process, Clayton falls from the tree when a vine is tangled around his neck, hanging him and killing him. Tarzan then accompanies Kerchak, who affirms him as his son and dies peacefully from his wounds.

The next day, Jane and her father prepare to leave on the ship, but Tarzan remains behind with the gorilla troop. As the ship departs, Porter encourages his daughter to stay with Tarzan, and Jane jumps overboard to meet Tarzan with her father shortly following her. The Porters reunite with Tarzan, and embark on their new life together.
