Knot-Wing the Koopa's Sky Fort
From the Super Mario Wiki
The level begins with an array of Bill Blasters, followed by some Koopa Paratroopas, and a Winged Cloud that summons many balloons for Yoshi to ride, up to a door and the first checkpoint. Yoshi must then traverse some Number Platforms while avoiding more Koopa Paratroopas and Bullet Bills. The segment leads to more Bill Blasters, along with many edible walls and the door leading to the second checkpoint. Another balloon rise follows, followed by a door leading to a platform rise and the boss door.
