Gust Jar
From Zelda Wiki.org
The Gust Jar is an item that sucks dirt, enemies, and elastic mushrooms (used to fling Link across holes) into itself. The Gust Jar will turn colors to indicate its power. It has a medium charge if it turns yellow, and turning red will indicate that it is at max power and will blow out the most air. This strange pottery is the main dungeon item of Deepwood Shrine in The Minish Cap.
The Gust Jar is also used for navigational purposes. While Minish size, Link can jump onto lily pads, then use the Gust Jar to shoot bursts of wind to propel the lily pad across sections of water.
The Gust Jar can also be used to suck in enemies and shoot them out, throw certain enemies off balance, absorb fire attacks, and remove fire scorching the ground. It's very useful for bringing hard-to-reach items towards Link.
Certain enemies such as the Lakitu and the Puffstool can only be defeated by using the Gust Jar. These enemies are often air-based.
