A Pyramid Ship
If a pyramid ship shows up, your planet is about to get flattened. No mercy. No warnings.
My teacher said, 'If you don’t behave, a pyramid ship will come and flatten this school!' I’ve been good ever since.
I was eating pizza when a pyramid ship landed. Now I’ve got pizza crumbs in my hair and a broken planet.
I told my little brother, 'You better behave or a pyramid ship will flatten us both!' He ran out of the room screaming.
