You have to detach the morph from its existing owner and then add it to 
the destination container. See grabMorph:from and attachMorph: methods 
for examples.

Also see senders of addMorph: and its variants addMorphFront:, 
addMorphBack: for more examples on how to embed morphs.

A Holder is essentially a PasteUpMorph with some options turned on. 
Other variants are Playfield, PartsBin etc.
