Laughing Gas Giant

There is a planet that has no floor;

It has no ground or solid core.

It has no land, but it does have mass;

It's made out of very dense laughing gas.

The inhabitants, well, they cannot fly;

They cannot teleport or glide.

They have no jets to self-propel,

And there’s never a breeze to give them help.

So they bobble and float quite helplessly

At the planet’s center of gravity,

Yet they seem amused in their crumpled mass —

Or maybe it’s just the laughing gas...
