The Ruins is the third world in Donkey Kong Country Returns and its Nintendo 3DS remake Donkey Kong Country Returns 3D. It was home to an ancient civilization, as evidenced by several of its ruins and monuments, and has still-running waterway and an artificial waterfall that travels into the sea. Stu is the boss of Ruins, and the Tiki Tak Tribe leader within the world is Gong-Oh. Ruins is accessed after clearing Beach, and is followed after by Cave.
Here DK & Diddy had to activate various mechanisms in the temples, destroy the rest of the Snaps ships, go through creatures that live in these ruins, devastate stone barriers and had the third battle against Gong-Oh to free Stu from his control.
|Wonky Waterway||In the level, there are several Rope Switches and then activate them.
|Button Bash||As the name implies, the level involves the duo having to activate buttons that change obstacles and open paths
|Mast Blast||The duo go to the seaside at the bottom of the ruins to destroy the last three of the Snap ships that are shooting cannonballs and explosive crates toward them.
|Damp Dungeon||The duo has to go through platforms embedded in water wheels without falling into the water. It is unlocked by buying the Map Key from Cranky Kong's Shop for twenty Banana Coins (or ten coins in the remake's New Mode)
|Itty Bitty Biters||Toothberries and their variants infest most of this temple, so the duo must be careful not to be caught off guard by these critters that lurk everywhere.
|Temple Topple||At this stage is very important for the duo to go with Rambi without losing him. Because it's full of stone blocks and Rambi is the only one who can destroy them.
|Shifty Smashers||This is the third Key Temple where the objective is to go through the blocks and traps to get the orb. For that, the duo have to complete the letters KONG in all the stages of the place.
|Boss level: Ruined Roost||In this battle, the duo must drop any type of bomb on Stu. Stu will drop a series of bombs, for example: bombs with a skull picture, others with a fire picture that will create a fire wave if it explodes, aerial bombs that will destroy the rocks below and Tiki Pops to chase.||Tiki Pop|
- Donkey Kong Country Returns Prima's Official Strategy Guide (page 19): The Ruins is the island's third world. These levels take place in the ruins of ancient civilizations that have been hidden away in a jungle. While you face several of the same enemies as you did in the previous worlds, you also face stilts, Toothberries, and Acks. As you travel though these ruins, look for hidden areas and pound on containers to get items. If you see a vine hanging from a statue head, jump up and grab it to pull on it. This will always cause something interesting to happen.
- In Jungle, there are ancient civilization-inspired structures similar to those in the Ruins world.
- The look of the monuments and architecture are inspired by Aztec ruins. By extension, the serpent statues are likely based on the Aztec serpent God Quetzalcoatl.
