What is needed to make a motion-activated sound player?


We see it all the time come Halloween time with cheap motion-activated gizmos that emit some random horribly recorded sound effect. I am trying to figure out how to set up a similar system, but something that uses custom sounds. I have 3-5 sounds that I would like it to play at random once activated by the motion detector. As a side note, I also need some red LEDs to light up once it is activated as well, but I figure that will be easier to figure out once I have the necessary components for the rest of the getup. So basically, does anyone have any ideas as to what I need and/or how to make it work? I tried looking up tutorials on this site, but I'm not even really sure what to look for. Thanks for your time!
