Shy Guy

Shy Guy appeared in 1988 video game called Super Mario Bros. 2. Shy Guys (alternatively formatted as Shyguys, Shy-Guys or ShyGuys) 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. Shy Guys are common in spin off games but are rare in the Super Mario series.
