Evil barrier

The Banana Bird Barrier is a large stone, gray wall found only in Donkey Kong Country 3: Dixie Kong's Double Trouble.

When Baron K. Roolenstein, under the guise of KAOS invaded the Northern Kremisphere he made sure the Banana Bird Queen would not mess with his plans. Using the Banana Bird Barrier, Roolenstein managed to trap the queen. After the queens imprisonment Roolenstein sent out the Kremling Krew to capture all the Banana Birds they could, as the Banana Birds where the only ones who could free their mother. Eventually almost all the Banana Birds were sealed away in the Banana Bird Caves, those Banana Birds that weren't captured took refuge with several members of the Brothers Bear family.

If Dixie and Kiddy Kong manage to obtain all the Banana Birds the birds will take the Kongs to their queen and mother. The birds will sing a song that will counteract the Banana Bird Barrier's power, the barrier will break and the queen will be freed.
