Design details: ​Off we went-whooshing around!
​ ​All I wished was to reach to Mars,
We all had a little party there,
Dancing eating and partying around,
The sun seemed like a disco light,
Venus & Neptune were having a fight!
When it was time for me to return,
I promised all the little stars,
Not to tell a single soul,
About my journey to planet MARS!!
