Boo Crew
Boo Buddy Swarms[1] are Boos known for grouping in masses to attack. They appear in Super Mario World and Yoshi's Story.
In Super Mario World, they are found only in the Donut Ghost House and Forest Ghost House. They are usually transparent, which is when they are harmless, but periodically will turn opaque, which is when they are dangerous, to dive at Mario. They are indestructable and the only way to deal with them is to run past them and enter another room.
In Yoshi's Story, they appear in Ghost Castle. These tiny ghosts will swoop at Yoshi very rarely, unless he throws an egg at one of the members of the group. Then, all of the Boos will stop in their tracks and swoop at Yoshi. It is impossible to defeat all of the Boos, as more will just appear off-screen. Unlike their Super Mario World counterparts, they don't turn transparent and can be destroyed.
