Spy Guy

Spy Guys are Shy Guys dressed in camouflage gear. So far, their only appearance is in Paper Mario, where they appear in the Shy Guy's Toy Box. They can attack Mario with either a slingshot or a hammer, changing weapons each time they are attacked. If Mario gets hit by the hammer and fails to guard against it correctly, he loses one of his action commands for several turns. Since Spy Guys always attack with a slingshot outside battle, they are hard to get harmed and Mario should be careful about them and he should use ranged weapons such as Kooper's Shell as if Mario gets to close, it will fire rocks in rapid speed which if Mario is unlucky, he will get hit by the First Strike.

Trivia

 * Spy Guys resemble Petal Guys from Super Mario World 2: Yoshi's Island.
