Big Guy the Stilted

This is a gigantic robotic red Stilt Guy who is a boss in the Yoshi's Island DS game. He may have been originally intended to be an actual Shy Guy at one point during the course of the game though. To defeat him Yoshi had to either use eggs or Baby Bowser's flame breath to knock it into the lava that surrounded the bottom of the area he was fought on. Then once he was in the lava Yoshi simply needed to ground pound him. This had to be done three times to reveal who was working the giant Shy Guy... regular Shy Guys.
