A Towel
A towel is like a magical blanket for space tourists. It can cover you, wrap you, and even fight monsters. If you wave it, you might get rescued by aliens.
My dad used a towel to fight a monster on TV. He said it was the most useful thing ever.
My sister wrapped her towel around her head during a thunderstorm. She said it kept the clouds away.
My uncle waved his towel and got rescued by aliens. He said it was the best day of his life.
