This song is a lullaby and has become the only way my 4 year old son goes to sleep, as a result I've made it longer. I've also added some humanity to it, so it's not just about not getting caught by the fisherman... enjoy-

YEA HO, LITTLE FISH

You just eat up a little seaweed,
The sea will provide for whatever you need.

You just swim away from the fisherman's net,
That fisherman catch fish, but don't catch you yet.

You swim and play in the big ocean waves,
You listen to your daddy (mommy, teacher, etc.) you don't misbehave.

You eat all your food, get strong muscles and bones,
You find a cute fish, have little fish of your own.

You just swim in and out of the pretty coral reef,
You watch what you do so you don't come to grief.

Soon this song will come to an end,
But you little fish will always be my friend.

(CHORUS) Yea Ho, little fish don't cry don't cry.
Yea Ho, little fish you'll be whale by and by.

And when you're a whale, you'll sport a great tail,
You'll swim way offshore where no fishermen sail.

Now that you have listened to me,
I have sung you the song of the fish in the sea.
