Knot-Wing the Koopa

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

- Kamek

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

In World 2, Yoshi can defeat Knot-Wing by tongue-grabbing 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. 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 are replayable in the Boss Tent.

Trivia
