Place the graham
cracker on a wire rack placed over a
cookie sheet. Cut a few of the
marshmallows into large pieces.
Arrange the marshmallows on top of
the graham cracker, using some
frosting to secure, to look like a tumble
of rocks. Heat the gray frosting in the
microwave, stirring every few seconds
until it is the texture of lightly
whipped cream. Pour some of the
frosting over the marshmallows to
coat. Spoon the excess frosting into a
resealable plastic bag to be used for
the elephant. Set rocks aside.
