Cloud Drop

Cloud Drops, also referred to as Blusties or erroneously Gusties, are cloud monsters that fly in a short line vertically or horizontally in Super Mario World 2: Yoshi's Island (and its remake), Yoshi Touch & Go, Yoshi's Island DS, and Yoshi's New Island. They appear in packs and in areas where a Yoshi can turn into a helicopter. They move quickly, but they can be defeated with a hit on the head. While their Super Mario World 2: Yoshi's Island artwork depicts them as a recolor of the Lava Drop, their sprites are distinct.

In Yoshi's Woolly World, enemies resembling Cloud Drops, known as Wiks, appear.

Super Mario World 2: Yoshi's Island

 * Player's Guide: Watch out for these wherever the billowy white stuff is found on Yoshi's Island.
 * Shogakukan guide: ゆらゆらと同じ場所を行ったり来たり. タマゴ投げで倒したり、食べたりもできる. (It wobbles back and forth in the same place. You can throw an egg to defeat or eat it.)

Yoshi's Island: Super Mario Advance 3

 * Shogakukan guide: ゆらゆらと同じ場所を行ったり来たり. 食べてしまうか、タマゴ投げで倒そう. (It wobbles back and forth in the same place. Eat it or defeat it by throwing an egg.)

Yoshi Touch & Go

 * Shogakukan guide: 空中の同じルートを、上下または左右に往復する. ルートをさえぎるように雲を描き、足止めしてから倒すといい. たくさんいるときは、雲で壁を作って、反対側に閉じこめてしまえば安全. (It will move back and forth along the same route in the air, either up and down or to the left and right. It is a good idea to draw a cloud to block the route, stop them in their tracks, and then take them down. If there are many of them, it is safer to build a wall with clouds and confine them on the other side.)

Yoshi's New Island

 * Shogakukan guide: 一定の区間を、上下あるいは左右に往復移動する. 移動速度は速めだ. とはいえ、移動区間をチェックしておけば、簡単に避けたり攻擊したりできる. (The character moves back and forth in a fixed section, either up and down or left and right. The speed of movement is fast. However, it is easy to avoid or attack if you pay attention to its travel path.)
