The Llama's Temple is an area in the Angry Aztec level in Donkey Kong 64. Lanky Kong's cage is located under the water here. Outside the temple is a Donkey Pad. Donkey Kong must use this pad to play a barrel blast challenge in order to free the temple's titular Llama from his cage. Once this has been done, the llama will return to the temple and the player can use him to cool the lava inside the temple. Other notable areas inside the temple are a room in which Lanky Kong can play a memory game with monkey heads and a room with lava accessible only by shrinking Tiny Kong or using the temple's second Bananaport Pad.
