The performer may assume the form of a doll. While in this form, the performer may not move, walk or talk unless the doll would be capable of doing so normally (needless to say, the modern age has made this Song somewhat more useful): however, the performer may still hear and see. Size and mass may be altered, but at a cost to maximum Body Hits:

1x to 1/4 mass: No change

1/4 to 1/16 mass: Body Hits/2

1/16 to 1/64 mass: Body Hits/4

…and so on. Note that reducing a 150lb vessel to a 2 1/2 pound doll will require a division of mass/weight by 64: using this Song to turn the same vessel into a 1/2 pound toy plastic robot will divide mass by about 256, and Body Hits by 8.
