Have a look at animations eg.
http://www.squeakland.org/pdf/etoys_n_authoring.pdfMake a holder with all colors respectively shapes etc, and change the
color respectively let it look like the according color of the shape
at the index of that other holder.
(Hide that holder if necessary). Change the index of the cursor of
that other holder according to the hunger/illness etc.
Meta hint: Post this kind of etoys questions _also_ to the squeakland
mailing list.

Guess the answer is: use the animations idiom again.

Don't understand exactly, but you can get a random tile by pressing
on the label of the object in any script.
Hope that helps,
