pocket sized sound maker?

you know one of those key chain kind of things that play sounds when you press a button? is it possible to make one of those or hack one to make my sounds?

It depends on the sound you want to make. If you just want to make an annoying beep, it's really simply to make. If you want it to play sound effects, then you're better off getting an MP3 player and some small speakers. It's hard to play sound effects with microcontrollers and actually get a decent result.
