I Will Build A Sandcastle

I will build a sandcastle,
it will protect me and everything
The best in the world,
made from the purest sand.
Raise my own flag,
invite my friends and have fun.
We will play and play
until it starts to decay,
and even wash away
then one day I'll say...

I built a sandcastle,
the best in the world,
made from the purest sands
and the handiest helping hands.
