The 3 Color Fighters are small monsters appearing in the two-part "Snack Attack" episode that, according to Customer Service, were designed to look like toys so they can play around with their enemies. Not only are they skilled martial artists, but they also have the magical ability to grow in the moonlight. The fighters came disguised as chocolate along with King Dedede's Martial Arts All-Stars. The Cappies were in for quite a howling when they put their 3 Color Fighters on their window sills and left them there for the moonlight to shine on them, and the toys grew bigger and came to life. The miniature monsters then went rampaging all over the town, and the Cappies discovered that the fighters could be destroyed in one hit. Kirby, however, made no attempts to attack the miniature fighters, but after he defeated all of the Martial Arts All-Stars, the Cappies freely destroyed the remainder of the small villains.
The 3 Color Fighters are small, miniature grey monsters coming in different shapes wearing different colored pants, wearing dark blue shoes, having different-colored hairstyles, and having flat yellow eyes. Unlike their names, they aren't just three colors, but actually four colors. The blue fighters are pyramidal with flat tops and pointy orange hair, the green fighters are orbicular with orange hair that comes down, the red fighters are trapezoidal-prism in shape with green hair that goes up, and the yellow fighters are simply blue fighters with upside-down bodies and spiky green hair. When destroyed, the fighters flash rainbow colors and disappear.
