栗山夕璃 - Spooky winds (Sub Eng)

You will probably see this song called a bunch of different names. Hyu~dorodoro is the sound a ghost makes when it appears, so not exactly a "boo". Dorodoro is often used to indicate something spooky and hyuu is an acute sound usually the wind or music.

Pokemon-related stuff in the video:
0:29 Grudge - A pokemon move
0:29 1,2 ... and ta-da! - This is a famous phrase that appears when you make a pokemon forget a move, the "ta-da" part is different for every language
0:47 Bitter Malice - A pokemon move
0: 49 Curse - A pokemon move
1:30 Pursuit - A pokemon move
1:31 Helping Hand - A pokemon move
1:35 Silph Scope - This pair of scopes was used in early games to identify ghost pokemons
