Super Mario Advance
They appear in early trailer of Yoshi's Story, though they are not present in the final game. They also appear in the Yoshi Demo, where stomping one would turn it into a regular Shy Guy. A giant robotic Shy Guy appears in Yoshi's Island DS. One also appears in the WarioWare: D.I.Y. Showcase microgame Mario Adv.
In the small short that concludes the chapter in volume 26 of Super Mario-Kun, a Giant Shy Guy attacks Mario, Goombario, and Kooper. It then pits Mario against Robirdo. Mario, however, grabs the Giant Shy Guy and throws it against Robirdo, defeating both.
Yoshi's New Island
Mega Guys also appear in Yoshi's New Island. Here, Yoshi can swallow them to turn them into Mega Eggdozers, which can be used to destroy otherwise indestructible obstacles. Mega Guys require a bit more effort than normal to swallow, as the player has to rapidly press to do it. A metallic variant known as Metal Guys also appear, which are used to make Metal Eggdozers.
