Shape Tweening Between Graphic and Text

Hello,
Iā€™m pretty new to Flash MX, but can produce some basic things. I have been experimenting with Shape tweening.

For a web-site I am creating, I want to go basically from a blob to some text.
The effect I want to try and create is a pool of liquid transforming to create the title of my site.

I have been trying shape tweening, but cannot make it work. Is there a way it can be done???

:ear:

Cheers
