Fishes and Snails

Every day I wake up weirder than the last.
I am a fish with scales instead of years.
I am a snail, body curled in a shell,
Born again every day
From orange and pink dust.
I breathe underwater
I tread on land
I can go days without food
Or change my name to Gluttony,
and the current will still take me on
and on,
and on,
and on,
until the end of time.
