Hi, lulu,

Just drag the morph over the parts bin flap and drop it into the 
interior of the open flap, and it will become available as a "part" 
in the flap.

If the first row/column of the flap is full, its contents will wrap 
to a second row or column; if this happens, just open the flap tab a 
little wider to see its full contents.  (Perhaps this is what is 
happening when the morph you drop appears to have "disappeared.")

Cheers,
