From the Danbooru wiki
Shy Guys, alternatively formatted as Shyguys, Shy-Guys, or ShyGuys, are recurring enemies that are recognizable by their masks, which they wear due to their shyness. Shy Guys first appear in Yume Kōjō: Doki Doki Panic, later released in the Western world as Super Mario Bros. 2.
