Silkie yer thinking of "Marine boy"
Its Marine Boy, Brave and Free!
Fighting evil 'neath the sea.
He is a boy, a very special boy
Powered by Propeller Shoes, flying Sub Ahoy!
Whooshing through the water on a friendly dolphin's back
Racing to the rescue of victims of attack.
In a flash, he'll foil the foe
With a quick boomarang throw!
Loyal friend of the sea to the end
Is our Marine Boy.
