Cloud Cuckooland

Cloud Cuckooland is a surreal area located in the cloudy skies. It is the eighth world of Banjo-Tooie and the last regular world. Banjo and Kazooie need at least 45 Jiggies to access Cloud Cuckooland. There are various platforms that float around in the world.

Unlike other levels, there is no door to Cloud Cuckooland. Instead, after Banjo and Kazooie complete Jiggywiggy's Challenge, Master Jiggywiggy uses his power to make a bubble appear in a small bump in the ground near the Wasteland of Isle o' Hags. The only way for Banjo and Kazooie to access Cloud Cuckooland is to enter the bubble, which then floats them up to the location. Cloud Cuckooland is the only main world to be disconnected from the other worlds and not have a Train Station.

In Cloud Cuckooland, Jamjars only teaches one move, Sack Pack.

Jiggies

 * 1) Inside the Pot of Gold: Get Mumbo and head back to the Central Cavern. Follow the cliff path right, up and above to the blue cave exit. Now, on Mr. Fit's Running Track, follow it forward and to the right, to the Mumbo Pad across from the Pot O' Gold. Use the Rain Dance spell to extend a rainbow bridge (and get the After the Storm achievement on XBLA). Take Mumbo back home then head back inside the Central Cavern. The easiest way is to Backflip over the left side wall then exit out the greeny/aqua cave door to get to the Rainbow/Switch. Once there, trip the switch, hurry across and enter. The platform in the middle has 4 eggs around it. Shoot the respective eggs into each hole to start the challenge. Using Rapid-Fire Eggs, shoot the Jiggies that line up on the wall (you have to hit 90 to win).
 * 2) Inside the Trash Can: Get Kazooie and fly/Glide to the Trash Can. Step on the switch and head inside. Guffo the can tells you to clear the Can of germs. Run around using the Wing Whack and you should win it. Alternatively, pick a strategic spot and switch to first-person view, then fire eggs at the germs. Dragon Kazooie's infinite supply of Fire Eggs is very useful here.
 * 3) Defeat Mingy Jongo: One of the two Mumbo Skulls in this level contains Mingy Jongo, a cybernetic impostor. Again, exactly which skull it is changes every time. Beat Mingy down to get this Jiggy.
 * 4) Canary Mary's Rematch: Arguably one of the hardest Jiggies not just in the game, but in the series. Outside Wumba's Wigwam is a small mechanical mouse, where a familiar bird Banjo and Kazooie know, Canary Mary is waiting for a rematch. She's a lot faster than when she was in Glitter Gulch Mine, which is not that helpful to Banjo and Kazooie. The key to win is to exploit Mary's unusual "rubber band AI", either by alternating going slow and fast, or by pausing the game during the race every now and then.
 * 5) Defeat All the Eyeball Plants: Grunty planted four Eyeballus Jiggium Plants around the world. Get the Bee and then shoot the flowers, each passing a Jiggy on to the other. One plant is near George Ice Cube, another is on the side of a large pool of water, another is above the red Mumbo skull, and the last one is below the Cheese Wedge. Only when all four are destroyed can you claim the Jiggy.
 * 6) The Zubba's Nest: Change into the Bee and fly to the top of the world. A statue of a Zubba holding a target is at the top. Shoot it, and then quickly shoot it 20 more times to enter the Zubba Nest. The Zubbas have you shoot Zubbas to get points, winning you the Jiggy as a reward.
 * 7) Find Superstash's Combination: Superstash, a safe in the Central Cavern, has lost his combination. He hid the 4 numbers in small holes (only accessible with a Clockwork Kazooie Egg). The first hole is down on its own ledge by the water near where George Ice Cube was. The second is on a ledge above Superstash, simply move the Kazooie Egg through the red tunnel. The third is at the top of the Central Cavern but the entrance is outside at the top of the mountain on a red platform. The last one is in a hole behind the Trash Can.
 * 8) Inside the Jelly Castle: As Banjo, and from the Split-Pad in the Central Cavern, head straight out the cave door in front of you and you should be at the blue Mumbo Skull. Climb the vine on the left, then use the flower that is right next to the vine to shoot you to the Jelly Castle. Use Banjo's Shack Pack to get into the Castle and get the Jiggy.
 * 9) Inside the Cheese Wedge: From the Central Cavern, Split Up, then as Banjo, head directly in front of you out the blue cave exit to the blue Mumbo Skull. Climb the nearby vine, Sack Pack or just jump really, across the path to the Floater. Assuming you've already hatched the egg, continue on to the other side. If not, pop back as Kazooie and Hatch the Floater. You'll find a patch of dirt in need of a seed. (The seeds are buried back at the first entrance, you will find them by using the Bill Drill.) Then, to make the Vine grow, perform Mumbo's Rain Dance again. With the vine ready, head up and into the Cheese Wedge as Banjo. Use the Sack Pack and hop onto a spiky platform that floats down. Drop onto a ledge in the far back area, and then use the Shack Pack to head through a small hole, where you find a Jiggy. Move quickly; the air inside the Cheese Wedge is toxic.
 * 10) Beat Mr. Fit: Mr. Fit, an aardvark wearing a jogging suit, is going to test you to see if you can beat him. First, he's behind the world entrance next to a large structure. You have to jump over the bar using the Springy Step Shoes, which can be dug up at the same spot where the seeds are. Grab them and then use the flower to shoot you back over, so you can hurry over and jump the bar. Next, Fit is above the red Mumbo skull. You'll need one of the seeds now to make a Vine to Mr. Fit. Go there as Banjo, and then when the race starts, use the Sack Pack to take the narrow path. The final test, is a foot race. Now transform in Kazooie and then follow the path up (the path near the Claw Clamber Footprints) to the top of the Central Cavern to the blue cave exit. But before you step through, continue along the narrow path to a little nook with some Turbo Trainers. Now, run outside to race Mr. Fit and finally get the Jiggy.

Jinjos

 * Inside the trash can, on top of the Snacky Fatty Chocs box.
 * In the central cavern. Reach him by gliding as Kazooie, or shoot a Clockwork Kazooie Egg up there to save time.
 * Inside whichever skull is Mingy Jongo's. (The real Mumbo Skull has a Minjo instead.)
 * In the rafters of Humba's tent.
 * In the cheese wedge.

Extra Honeycombs

 * Bill Drill the spots at the start of the level
 * Behind the Pot O'Gold
 * Handle of the Trash Can

 * 75 points or more in the Pot O'Gold game.
 * Defeating Canary Mary twice.
 * 40 points or more in the Zubba's Nest game

Treble Clef

 * At the top of the Central Cave only accessible by a cave near the top of the mountain on the outside.

Jamjars Locations

 * In the Central Cavern, Kazooie must hatch the Floatus Egg that is located right by the Split-Up Pads. Then Banjo alone must use Taxi Pack on the Floatus to float across to the platform where the red jelly wall is. Banjo then must use the Shack Pack to get through the small hole to reach Jamjars.

Glowbos

 * Inside the Central Cavern in a small, elevated pool overlooking a larger pool
 * In a large pool attached to the central cavern where George Ice Cube is also found.

Banjo-Kazooie: Nuts & Bolts
"Cloud Cuckooland was the last challenge world of Banjo-Tooie. It took L.O.G. a lot of effort to get running smoothly due to its large, open nature, and was where Banjo met Mr. Fit."

- Banjoland description

A painting/model of Cloud Cuckooland makes up its own area in the third world, Banjoland, of Banjo-Kazooie: Nuts & Bolts. It appears alongside the Rubbish Bin and Cheese Wedge. On the painting, there are also models of the Red Jelly Castle, the Cheese Wedge, a Mumbo's Skull, a few rainbows and an Eyeballus Jiggium Plant. Interestingly, there is also a red stop n swop egg perched on one of the outcrops, that when smashed releases a Gruntbot.

Trivia

 * In real life, the term "Cloud Cuckooland" is used to describe a realm of fantasy, dreams, or impractical notions that are beyond the comprehension of the real world, which explains the level's surreal; childlike appearance. It is also the name of a location in the 2014 animated film The LEGO Movie.
