The Olympic Pufferfish rides Again

I once won a silver, a bronze and a gold,
I once had to sleep on the ground where its cold,
with creatures all round me and air that was damp,
and awoke in the mornin with terrible cramp,
but none of it matters cos lifes just a dream, 
and like it or not we're just fish in the stream,
where the waters run shallow but sometimes run deep,
and among all the weeds all the predators creep.
So what? if they spot you, so what? if they pounce,
I'm the cool puffa fish with incredible bounce!!
I'll just puff up my chest and look big and feel proud,
I've got spines of my own that'll make them scream loud.
I just live it and love it and waste no time frettin,
and buzz to the max when my fins get a wettin,
i'll swim down the middle and take the full force, 
of the current that hits me in lifes watercourse,
its the only true path that i know how to travel,
go too near the bottom and scrape on the gravel,
go too near the top and get ate by some creature,
a visual enactment of some horror feature,
Remember your worth, your compassion and honour,
an dont worry about nets, YOU CAN SWIM WHERE YOU WANNA!!
