Castle of Big Guy the Stilted

Castle of Big Guy the Stilted is the World 4 castle, appearing in Yoshi's Island DS. The boss of the castle is Big Guy the Stilted, a Shy Guy-operated robot. The player plays as Blue Yoshi in the level. Blue Yoshi uses two fire-proof stilts throughout the level that help it cross the lava. After clearing the level, a cutscene tells of Bowser's plans to take over the world and explains the story of the star children.

Layout
Yoshi starts the level in a castle area with a Stork Stop, an Egg Block, and some Stilt Guys nearby. A nearby pipe leads to a room where Yoshi must use a pair of stilts to walk across the lava and break a vase containing a key. The player must go back and open the locked door which reveals an area in which Baby Mario must use a Super Star to get to the other door. Here, the player must avoid some Zeus Guys and enter a door which leads to a Stork Stop, a Middle Ring, an Egg-Plant, and a wall of spikes. Beyond the wall is a key which must be used to open a locked door, with the area housing a boss door. In it is Big Guy the Stilted, who can be defeated by knocking him off the platform and ground pounding his head. When the robot is defeated, Yoshi can access the next level.

Trivia
In the background of the castle, it is revealed that this castle is where Shy Guys get all their training (they also train in Yoshi Tower). It appears to be something similar to a school. In the castle, they appear to be taught how to walk with stilts and they are taught about who Yoshi is. It is also here that they grow Piranha Plants. There also appears to be a Drying Room, where the Shy Guys hang their wet clothes and leave them there so they dry. Shy Guys use ladders to travel around the castle, although Yoshi does not get to use ladders.
