Tarzan and the Face from the Past
While Tarzan teaches Zutho and his friends how to make spears, a fire broke out and nearly destroyed the jungle but the rain put it out. Tarzan blamed himself and ended up in Zutho's debt. Several years later, Zutho resurfaces in order to get Tarzan to fulfill his favor into dealing with some annoying howler monkeys that were keeping him and his friends up at night. With help from Jane, Terk, and Tantor, Tarzan did the right thing and admitted what happened the day of the fire to Kala, who then processed to punish Zutho.
