Smiley Flowers

 * Smiley Flower #1: In the cave with three bows in the ground, the player should lick the third. This will reveal a small underground room with the first Smiley Flower.
 * Smiley Flower #2: After jumping on the Spring Ball, the player should jump from the windmill over to a cloud on the left. This cloud leads the way to a second cloud which has the second Smiley Flower.
 * Smiley Flower #3: The player will find two Warp Pipes with three clouds between them. When you jump down to the bottom cloud, it reveals a hidden Winged Cloud, but also makes two Gusties appear. Dodge the Gusties and pop the Winged Cloud to get the third Smiley Flower.
 * Smiley Flower #4: Between two windmills, there is a small platform with a Piranha Plant. Defeat the Piranha Plant to reveal a bow. After licking the bow, it will fly away and attach to a hidden piece of land. Lick the bow again to find the fourth Smiley Flower.
 * Smiley Flower #5: On the last windmill, throw Yarn Balls at all four platforms to reveal the final Smiley Flower in the center.

Wonder Wools

 * Wonder Wool #1: Between two windmills, there is a platform with an Egg Plant. If the player jumps from one windmill to the other, over this platform, they will find the first Wonder Wool.
 * Wonder Wool #2: After the Egg Block, the player will find two trees with bows. After licking the second, the bow will fly over to a section of land. If the player licks the bow for a second time, it reveals the second Wonder Wool.
 * Wonder Wool #3: The player will find a windmill after a blue Warp Pipe blocked by a platform. There will be a frame of a warp pipe to the left of the windmill. Throw a Yarn Ball at the frame to make a Warp Pipe, then go down it. Inside the secret room, the player will find six flowers. Throw Yarn Balls at all six, then Beads and the third Wonder Wool will appear.
 * Wonder Wool #4: In the middle of a windmill there is a Winged Cloud. Pop the Winged Cloud and the fourth Wonder Wool will appear.
 * Wonder Wool #5: Climb up a windmill next to a small cave. At the top, jump onto a small hidden platform with a Flipper and the fifth Wonder Wool.
