The Battle for Teeka

Discovering bullet cartridges in his deceased father's cabin, Tarzan takes them with him as curios. Subsequently, Teeka is taken by an ape from another tribe, and Tarzan and Taug join forces to trail the kidnapper and rescue her. When they catch up, they are surrounded by the enemy tribe and nearly overwhelmed, until Teeka throws the cartridges at their foes in an apparently futile effort to help. When some of them hit a rock, they explode, frightening the hostile apes and saving her "rescuers".
