Knitty-Knotty Windmill Hill is the fifth level of Yoshi's Woolly World. It features the first appearances of moving wool platforms in the form of windmills.

Layout
The level starts off next to a windmill, before an Egg Block and a windmill which needs its platforms filled in. After this are another two windmills which also needs platforms filled in, before leading to a Winged Cloud with a Spring Ball inside of it, which will allow the player to climb up a larger windmill, which leads to the next area.

The next area takes place in the sky, and the player will have to jump over clouds and windmills whilst avoiding Shy Guys and Gusties. Midway through this section is a Warp Pipe that needs to be filled in, this Warp Pipe leads to an area where the player needs to sprout all of the flowers, before filling them, when they do this they will be rewarded with beads and a piece of Wonder Wool. At the end of this section is a Warp Pipe. The next area is filled with windmills that need platforms filling in so the player can progress, and the end of this section is the Goal roulette.
