Duplicate and remove movie clips randomly

Hi

I want to make a sparkler button that shows twinkling stars around the button in random positions.

I have made two types of stars (movie clips)

1 - twinkle: this movie clips shows a star appear and disappear with some rotating and alpha channel so the overall effect is like twinkling and revolving star.

2 - same effect star moving on a small curved path.

now I want to use action script for onMouseOver event to duplicate these two movie clips in different X Y positions (very close to each other) with a magical sound. I can do the sound part :slight_smile: but not the actionscript part in which i want to duplicate both clips in random positions and then remove them (if that is necessary to free the resources they are occupying) however the stars affect have a fade in and fade out effect so they disappear automatically.

any help is highly appreciated.

thank you.
