I've only been able to do this by changing the protocols in normal 
Smalltalk code.

For an example of how to do this, look at my RCXMorph change set, 
which is at 
http://minnow.cc.gatech.edu/squeak/uploads/2412/RCXMorph-nk.1.cs

This may require other change sets from
http://minnow.cc.gatech.edu/squeak/2412 to operate.

Basically, the formula is:

* define some new methods in Player to do what you want. These may 
talk to the costume (the Morph)

* define methods in the appropriate Morph class(es) if necessary to 
support those Player  methods

* define additionsToViewerCategories in your Morph class

* run "Vocabulary initialize"
