Flapper the Parrot
From the Super Mario Wiki
Flapper the Parrot is a blue parrot found in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2.
Flapper only appears in one level in both games, called "Parrot Chute Panic". Here he aids Diddy and Dixie Kong be grabbing onto them and slowly descending down a large Zinger hive. Though Flapper's assistance seems unecessary it is actually quite needed as without Flapper the Kongs would descend the Zinger hive uncontrollably and probably land on a Zinger or something equally nasty. It is sometimes easier to use Dixie Kong to float down though.
[edit] Name Controversy
The name Flapper is derived from one of Swanky Kong's Bonus Bananza rounds in Donkey Kong Country 2. When asked what their parrot buddy's name was, the player were given the choice between Squawks, Squeaks, and Flapper. The last two names became fan names created by Donkey Kong fansite Donkey Kong Universe for the blue and purple parrots, respectively, though the latter has now been officially named Quawks the Parrot.
