Free Halloween Sounds (free) is just plain fun, what it is is fifteen free spooky sound effects (bats, ghosts, chainsaws, creaky floors, etc) and a spooky soundtrack you can play in the background. To kick it up a notch just get a mini jack to 1/4" stereo jack and plug it into your sound system for Halloween and really give the kids a fright! I've been playing with this thing so much even my son is getting tired of it, and he's 7!
