Secret cave

Banana Bird Caves are caverns located all across the Northern Kremisphere.

When Baron K. Roolenstein, under the guise of KAOS invaded the Northern Kremisphere, to make sure he was unopposed, sealed away the powerful Banana Bird Queen. To make sure the queen couldn't escape K. Rool had the Kremling Krew hunt down and capture the queen's various children, the Banana Birds. Though the Kremling Krew didn't capture all the Banana Birds they did obtain the bulk off them, these Banana Birds the Kremling Krew sealed away in caves located all over the Northern Kremisphere.

During the events of Donkey Kong Country 3: Dixie Kong's Double Trouble!, Dixie Kong and Kiddy Kong, on their quest to find the missing Donkey Kong and Diddy Kong would sometimes stumble upon a hidden Banana Bird Cave. In order to free a crystal-imprisoned Banana Bird the Kongs would have to play a memory game with flashing red, green, yellow and blue crystals. The crystals would flash in a sequence which the Kongs must copy. If they copy the sequence correctly they will free a Banana Bird, if they fail they will have to try again. As the game progresses it becomes increasingly difficult to free a Banana Bird due to the crystal sequence flashing at a much faster pace and increasing in length.

Occasionally the Kongs may need help to reach Banana Bird Caves, this help often came in the form of members of the Brothers Bear family. In exchange for a favor or something similar a bear may sometimes open the path to a Banana Bird Cave.

If the Kongs manage to free all the Banana Birds they will be able to free the imprisoned Banana Bird Queen from the Evil Barrier.

Aside from the aforementioned Banana Birds and flashing crystals there is not much in a Banana Bird Cave, though what looks like tunnels can be seen in the background of the caves, leading to the possibility that the caves are inter-connected to one another.
