Knot-Wing the Koopa

"Knot-Wing, you're up! Swoop in from above and SQUISH THAT YOSHI."

- Kamek

Knot-Wing the Koopa is an enlarged Koopa Paratroopa boss in Yoshi's Woolly World. He serves as the mid-boss of World 2. He also reappears in World 4 and World 6. In all three battles, his primary attacks are Ground Pounding and dashing inside his shell.

In World 2, Yoshi can defeat Knot-Wing by licking the knot on his neck at the right time when he is on the ground, while he is performing his Ground Pound attacks. After doing so, Knot-Wing will flip over onto his back, exposing the bandages on his underside, allowing Yoshi to attack him with a Ground Pound. In World 4, Yoshi must allow Knot-Wing to slam into a broken part of the bridge, which accidentally causes him to touch the spikes at the bottom of the water and flip over to reveal his weak spot. In World 6, Knot-Wing can only be defeated when the Bill Blaster on his back is hit with a yarn ball thrown by Yoshi instead of untying a knot on his neck.

All three boss battles with Knot-Wing can be replayed in the Boss Tent.

Trivia

 * Knot-Wing is the only Koopa Paratroopa that can regain his wings after losing them. This trait is shared with Parabones.
 * Knot-Wing the Koopa may be a winged homage to Hookbill the Koopa, a boss from Super Mario World 2: Yoshi's Island. Both Knot-Wing and Hookbill are red Koopa Troopas that are enlarged by Kamek, with their shells being particularly larger than the rest of their respective bodies. They share a similar naming scheme in both English and Japanese as well.
