Mini-Neckies are a miniature species of Necky that have appeared throughout the Donkey Kong series. They first appeared in Donkey Kong Country. The only notable Mini-Necky in the series is Krow who acted as a boss in Donkey Kong Country 2.
Donkey Kong Country/Land
Mini-Necky debuts in Donkey Kong Country alongside regular Neckies. Despite being a mere "Mini-" species, they could be considered more threatening than regular Neckies because they have the ability to fire small, deadly coconuts from their mouth at a moderately fast rate. Mini-Neckies were somewhat rare in comparison to their adult superiors.
Mini-Necky return in Donkey Kong Land, with all their traits from Donkey Kong Country.
Donkey Kong Country 2/Land 2
The Mini-Necky return in Donkey Kong Country 2: Diddy's Kong Quest, now simply called Necky due to the absence of their larger brethren. Here they were also semi-rare enemies found in some levels. Mini-Neckys have a different role than their Donkey Kong Country incarnation; instead of shooting coconuts, they simply dive forward in the direction of the Kongs when they come too close. This makes the Mini-Neckies somewhat like the regular Necky. Also fitting with the darker pirate theme, the Mini-Necky now wear bandannas and have a deeper voice (heard when diving). Also, a Mini-Necky boss by the name of Krow appears as the first boss, oddly seen before any of the regular Mini-Necky. There are also ghost-like Mini-Neckies called Kreepy Mini Neckies.
Mini-Necky reappear in the game's follow up game Donkey Kong Land 2, unchanged alongside Krow.
Mini-Neckys return after a period of absence in DK: King of Swing and DK: Jungle Climber. Mini-Necky here has it's attacks from both Donkey Kong Country and Donkey Kong Country 2; they either swoop in or shoot coconuts. Mini-Neckies also appear inside green balloons as items in Donkey Kong Barrel Blast.
