Hanging Blow Hard
From the Super Mario Wiki
Hanging Blow Hards are enemies that appear in Yoshi's Island DS. These Blow Hards stick to the ceilings of many areas in the game, and dangle vines from their mouths that Baby Donkey Kong can grab onto and use to swing to higher areas. However, these are very dangerous to climb on, as an unlimited supply of Needlenoses spout from its mouth as well.
They appear in the Island Museum, where they are displayed in the Botanical Enemy Exhibit.
