Knife Guys are Shy Guys that appear as enemies in Yoshi's Crafted World. Like Ninja Guys, they are present in every Ninjarama stage.
Most Knife Guys are encountered normally on Yoshi's path, but some appear from behind shoji-like doors. They carry ninja swords, which they point in front of them while running. When they bump into a wall or another Knife Guy, or simply encounter a platform's edge, they stop for a short time before turning the other way and continuing to scurry. Yoshi receives damage if he gets run into by a Knife Guy, although he can defeat the enemies by using any attack method.
In Outer Orbit, there is a space-themed skin of Knife Guy, along with several other Shy Guy types. This Knife Guy wears silver clothing and a space helmet, and hops out of spaceships wielding space swords resembling glow sticks. However, it acts in the same way.
