Iguanagon

Iguanagon is a large lizard enemy that appears in the game Donkey Kong: Jungle Beat.

It first appears in Silver Snow Peak. It chases Donkey Kong and Hoofer up a hill, while a snowball (that is rolling up the hill very slowly) blocks their way. The only way to get up the hill is to stay between Iguanagon and the snowball, while attacking the snowball with your clap attack. Eventually the snowball will bust, and Donkey Kong will reach the top of the hill. Iguanagon can not chase him as well over flat ground, and soon he gives up the chase.

Iguanagon later get's his own level, "Iguanagon's Realm", where Donkey Kong (riding Hoofer once again) actually has to fight him. Hoofer will run into a cave, where Iguanagon will be seen crawling quickly along the ceiling. Donkey Kong will chase HIM this time. The only way to hurt him is to throw a Pineapple at him. Every once in a while, Iguanagon will disappear into a hole in the top of the cave, and hundreds of birds will come out and throw exploding balls at the hero. After a while, Iguanagon will come back. If you do enough damage his body will start smoking. After a lot of damage it will explode, leaving only Iguanagon's head, which will promptly fall to the ground and explode as well.

Iguanagon also appears in the ending segment of Asteroid Belt. You have to fight it here as well, but this is optional, as as soon as you fall off the level ends. It is unknown what happens if you are able to defeat it while jumping over huge gaps.

Trivia

 * Iguanagon's name is probably based on the name of the ancient dinosaur Iguanodon.
 * Iguanagon slightly resembles a Wario World monster.
