Lime

Limes are green stick women who somehow joined the Slush Invaders. They wield shotguns, although Drabs have proven themselves to being able to wield shotguns (and other guns) as well.

Slush Invaders (movie)
Limes only appeared near the end of the movie, where they were killed by Stick JK in an attempt to keep him, Westick, and Joshtick from reaching Standrew who was held captive at the time. The Limes did not make a major appearance due to this.

Slush Invaders: Game
Limes were scrapped and replaced with Cobalts, so they never made it into the game.

Limes were supposed to be in the game as support to  Blues and Drabs but were replaced with the Cobalt. Cobalts have high HP and defensive properties, therefore they were better for supporting Blues than Limes.

Slush Tile Rush
Limes officially return in this third game of the Slush Invaders series. They also have their new designs, alongside their shotguns, as well as their gender being revealed as an all female group, much like the Azures.

They can be encountered in the level Land of the Rising Lime during the first gameplay run, but can later on be encountered in any level before Hazy Home Screen. A new type of Lime is also introduced, who appears to be the leader named Armored Lime.

Trivia

 * It's unknown how Limes managed to join the Slush Invaders if they were not Blue. However, it is possible that they were just hired mercenaries similar to Drabs.
 * They are named after fruits and their own color, lime.
 * Limes' shotguns resemble the Spas-12.
 * In the third game, Limes are revealed to be females and seem to be an all-female group, similar to the Azures.
 * There are also Armored Limes who appeared in Slush Tile Rush.
 * In the movie, they are Big Blue's minions but in Slush Tile Rush, they have a quote that says "Screw blue paint, I paint with BULLETS".
 * This could hint at a rivalry within the Lime Group and the Blue Baddies. This could also hint that their cooperation with them in the first movie was likely done begrudgingly.
 * The Armored Lime seems to be the boss of the Limes or at least a commanding officer.
 * Limes and Azures are the only all female enemy groups in the series.
 * The Limes appear to live up in the clouds near the sun, a level in Slush Tile Rush that is called "Land of the Rising Lime".
