Swimming Hole

I found a secret swimming hole And next to it a grassy knoll The water was so blue and deep Mesmerized I fell asleep And in my sleep I dreamed a dream That nothing was as it would seem I dreamt of sunken treasure At such a depth u could not measure And in my dream I was a fish And I swam guard Swish swish swish I can't explain what drove me to But in my heart I just knew I must protect this loot because That is what a guard fish does
