Cloud Cuckooland is the eighth world found in Banjo-Tooie. To find the bubble necessary to enter Cloud Cuckooland, one must search a crack in the Wasteland of the Isle o' Hags. It also ought to be noted that this is the only level in the game (barring Cauldron Keep and Spiral Mountain) that isn't interconnected to any other levels and has no train station. This is for obvious reasons due to the fact that Cloud Cuckooland is high above in the clouds and the only way to travel between Cloud Cuckooland and the Isle o' Hags is via the bubble.
