Foofers made a button-triggered sample player using Arduino + Wave Shield for use as a sound effects enhancement for costumes –

In the example here I’ve got a different animal sound attached to each button on a keypad…but it’s very flexible in that regard, you could use magnetic switches in a glove to trigger different sounds, or pressure sensors in the feet to make stompy noises, things like that.
