Mouse detecting the correct MC

Hi,
I am tring to create a “find and destroy” game…
I have 20 ball shaped movie clips…they move around randomly…I want to click(destroy) the ones having certain names (enemy1,enemy2…enemy8)or having certain color…
how can I write a function so that can explode them clicking with my mouse .

onClipEvent(enterFrame)//on(Press)
{
if(this==enemy1)
{
unloadMovie(this);
//do something;

}

}
