A Hot Air Balloon is an item introduced in and exclusive to Donkey Kong Country 2: Diddy's Kong Quest. Hot Air Balloons are blue balloons often found floating over hot lava and steam, in the world Crocodile Cauldron, specifically, the level "Red Hot Ride".
These balloons are vital means of transportation in that level, as they float over the lava and can be directed. The balloons fall slowly and if steered into steam they float upwards. Often one hot air balloon will lead to another and another until solid ground is found.
