Editing King Bowser's Castle (Yoshi's Woolly World)

After two rooms that serve largely as playable cutscenes, the level has a hub room requiring Yoshi to fill in statues of [[Baby Bowser]] with specific colors. [[Shy Guy]]s of the relevant colors can be found in certain rooms. Nearly every other enemy in the level cannot be eaten or is colored black, which conventionally forces the player to find all of the non-black Shy Guys to complete the course. Once complete, Yoshi has to complete an autoscrolling room where [[Kamek]] attacks him. At the end Yoshi fights Baby Bowser to rescue the Yoshis and end the game.

The level begins with [[Skeleton Goonie]]s and [[Winged Cloud]] hiding a [[cannon bobbin]]. This bobbin shoots Yoshi into [[Bowser's Castle]]. A segment containing black [[Fang]]s and [[Tap-Tap]]s follows, leading to a door. This door leads to a room where the floor rises into another room, which contains Baby Bowser statues in front of a large Baby Bowser statue in the background. There are two on the ground and two on a bridge in the room. Yoshi must fill in these four Baby Bowser statues with a [[yarn ball]] matching their color, otherwise the statue will revert to normal partway through filling. The bottom right statue needs red, the top left statue need white, the top right statue needs green, and the bottom right statue needs blue. There are Shy Guys of each of these colors in four rooms in the level, requiring Yoshi to eat most of them and return with their yarn balls. The Skeleton Goonies from the first room can be used for the white color if the player plans ahead. It is possible for Yoshi to be one of the required colors, allowing players in co-op or using Double Yoshi to skip one or two of these statues by throwing a Yoshi at them. Alternatively, in ''[[Poochy & Yoshi's Woolly World]]'', the [[Poochy Pup]]s ignore this mechanic and fill in the statues with the right color all the time. Once this task is complete the large statue in the background will briefly come to life and open its mouth, revealing a door into the next segment. As such, this room serves as a hub for most of the level. There are two [[Checkpoint (Yoshi's Woolly World)|Checkpoint]]s in the room that Yoshi can use to save his current progress, one on the far left side and the other on the far right. They are placed such that Yoshi can leave this room without touching either Checkpoint. Their arrows point toward the center of the room. There are also some black [[Hook Guy]]s on the bridge.
