Dear Mr. Sneeze,
 
You are correct.
 
�What�s he/she look like?� = �What does he/she look like?�
 
I have spent a considerable time researching every Contraction it is possible to make, for a Worksheet which I am preparing.
 
Randolph Quirk et al, �A Comprehensive Grammar of the English Language�, page 132, state: �Occasionally, does is contracted in informal style to �s, for example, �What�s it matter?�  (�What does it matter?�)
 
Here are some sentences written by me this evening, impromptu, in very informal style, using the word �does�, in the contracted form.  I agree that they are unusual, but they are not impossible.
 
1.       How�s he manage to do it?                         How does he manage to do it?
2.       What�s she do for a job?                            What does she do for a job?
3.       When�s he start his job?                             When does he start his job?
4.       Where�s she work?                                     Where does she work?
5.       Which�s he use most often, this or that?    Which does he use most often, this or that?
6.       Who�s she resemble?                                  Who does she resemble?
7.       To whom�s he owe the money?                  To whom does he owe the money?
8.       Why�s she do this every time?                    Why does she do this every time?
 
I hope that this helps you.
