Not to be confused with Swoopy.
Swooper Doopers are an enemy in Donkey Kong Country: Tropical Freeze. They are agile, white and red feathered birds with slightly exhausted/nervous expressions on their faces. They will continue to try and attack you by swooping a specific pattern. They can easily be defeated by jumping on them once, however, this may be difficult for inexperienced players, because they can be fairly quick.
