A Rock that Moves

You just happen to be
a rock that moves,
You are a rock,
Tigger
that became a cat
for awhile,
Sugar Plum,
and you are owned by
this mouse in a cave,
Pookey Bear
and there will be
no trace of you;
you will be vapor,
water vapor,
and I can say you will
flow to the sea.
Oh how trite,
the sea
the trite
meaningless
sea
it cannot
or will not
