Daggers are Stucker's weapons in the movie, the game, Slush Invaders: Duel and Slush Tile Rush. They are mostly taken from Warcraft's Rogue Class, as Stucker's abilities reference that game. Even though Stucker used hand-to-hand combat in the movie and Slush Invaders: Duel, those weapons have become close to him.
Slush Invaders (movie)
Stucker activated his daggers at some point during a fight scene at the beginning of the animation, then began slashing multiple blues with them. Once him, Stedro and Stickyle were captured by the invaders, the daggers weren't seen again.
Slush Invaders: Game
Stucker is unlocked after the Slush Fighters demolish the invader's giant mascot robot, The Robo Hokie. With that event, Stucker's abilities are revealed. Stucker automatically damages enemies on the ground with his daggers while he has limited health. His ultra, Blade Flurry, sends many daggers flying around him.
Slush Invaders: Duel
Stucker began using his daggers when he and Sthomas got up upon a massive tower in an arena that was owned by the invaders. Stucker utilized his daggers for the rest of the animation, even going as far as using his Ultra Attack.
Slush Tile Rush
