The star that fell

The star fell from the sky, burning like a matchstick. Down, down it went, getting ever smaller.
By the time it hit the lake, it was a sizzling stone the size of a mouse.
It reached the bottom, and then did something unusual.
It moved.
Emitting a brilliant light, the star rolled through the muck toward the shore. Still sizzling as it left the water, bits of the star crumbled as it came to a stop.
The remaining bits stretched, moving more like liquid than stone as it took the shape of the first creature it saw on the beach.
Which happened to be a mouse.
New whiskers twitching, the star-mouse sat back on its haunches and tilted its head up to the night sky.
"Landing successful." The star-mouse said, sending its words out in a beam of light. After a few minutes, a star in the sky flickered as another beam of light shot down to the star-mouse.
"Reduce your luminescence and proceed with infiltration." The words entered the star-mouse's mind and were tinged with a lime green that marked them as coming from the bright commander.
It took some time, but the star-mouse figured out how to dim its light to a mere glimmer. Then it scurried away from the lake, toward the human city it had last seen from far above the earth.
