Nebulous Streams Clouding My Brain

I sail on an ocean of custard and jam, Aboard a ship made of biscuits and bread. I am the sweet toothed pirate I am, And clearly not right in the head. Nebulous streams clouding my brain, Give me some peculiar thoughts, I wear a vest made of liquorice sticks, And a pair of marzipan shorts. With my motley crew of gingerbread men, Who are armed to the teeth with balloons, We go round the world, kidnapping cakes, While we gorge on sweet macaroons.
