Tiki Tong Tower

Tiki Tong Tower is the massive structure in which the Tiki Tak Tribe was sealed and it is the final area of Donkey Kong Country Returns.

Story
After the volcano of Donkey Kong Island erupted it awoke Tiki Tong Tower from its slumber, thus freeing the Tiki Tak Tribe from their imprisonment and allowing them to proceed with their evil plans. Throughout most of the story, Tiki Tong Tower does not directly interfere with Donkey Kong or Diddy Kong's journey, instead preferring to observe and monitor DK's progress from its volcanic domain.

After Donkey Kong successfully defeated the Tiki Tak Tribe's forces he went straight to the volcano's top to directly challenge the leader of the Tiki Tak Tribe who dwelled within the Tower, but before doing so he needed to traverse the dangerous obstacles constructed on the surface of the Tower with the aid of his Rocket Barrel.

After a hectic ride through the Tower's dangerous obstacles Donkey Kong made it to the maw of the Tower to challenge the Tiki Tak Tribe's mastermind directly and after a long battle he finally defeated the Tiki leader who then released a large explosion that sent DK flying high into the sky, but knowing that the Tower still remained DK used a powerful punch on the Moon causing it to fall out of orbit and crash land on Tiki Tong Tower's head which caused it to sink back into the volcano and explode into an eruption of bananas which sent the Moon back into orbit and finished the Tower off once and for all.

Trivia

 * It is unknown if the Tower is a sentient individual or if it is merely a physical extension of Tiki Tong's will.
