Mac Drawing program

When I first used a Mac in the early 80s there was a neat drawing product that could produce all sorts of great little pictures. It was part of the standard package.

I have just gone to create a drawing (outline of a tongue, showing taste centres) and have scrolled through all the standard software that comes with Tiger, and can't find anything.

Am I just not seeing what is there, or is there some other recommended download I should find?

(It just shows how often I get artistic, to have only just noticed..... lol)

Thanks for any suggestions,
Suzanne
