D.D.

D.D.s (short for Dangerous Duck ) are common enemies in the Wario Land series for the Game Boy. They are members of Captain Syrup's pirate crew, the Black Sugar Gang. D.D.s are anthropomorphic ducks, wearing striped bandanas and goggles. They wield a boomerang as a weapon and their attack pattern is reminiscent to that of a Boomerang Brother.

Wario Land: Super Mario Land 3
D.D.s first appear in Wario Land: Super Mario Land 3, where they try to hinder Wario on his quest for treasure on Kitchen Island. When one spots him, it will stop walking, hit its boomerang on the ground three times, and then throw it at Wario, damaging him if it hits him. They can be stunned and picked up, though they are among the heavier enemies in the game owing to their size.

Wario Land II
The D.D.s return in Wario Land II. Their attack pattern remains exactly the same as it was in the previous game, though they and their boomerangs are physically smaller by a small amount, and the latter spin faster. Like the previous game, they are classified as heavy enemies in this game, meaning that Wario will slow down significantly when carrying one. In the Game Boy Color version, they are given an orange, mint green, and dark blue palette.

Additionally, an unlockable minigame known as Flagman D-D can be accessed by completing the game with 100%. It features a D.D. as a host, along with a white puff and a Gugi. The minigame itself was a remake of the Game & Watch title Flagman.

Ducks
Wario Land II features a special type of D.D. referred to simply as a duck, although they are not stronger than regular D.D.s. In the Game Boy Color re-release, the ducks are given a deep red, blue, and black color palette to indicate their special status; however, they look identical to regular D.D.s in the original Game Boy version. They only appear in Defeat four ducks!, where the level's objective is to seek and defeat each of them.
