Shy Guys are timid troublemakers and common enemies in the Mario and Yoshi series. They are recognizable by their masks, which they wear due to their shyness. They made their first appearance in Yume Kōjō: Doki Doki Panic, a non-Mario game; they were later carried over to the Mario universe when Super Mario Bros. 2 was created. They are voiced by Treehouse member Nate Bihldorff.
