Leo stood on his step stool in the bathroom, watching his dad brush his teeth. The faucet ticked-tick-ticked as steam fogged the mirror.
He tilted his head. Why does his dad do this twice a day?
At breakfast, Leo asked his mom about it. She leaned in close.
Tiny food bugs throw parties on your teeth after every meal. They like to stay and party all night.
Leo marched to the bathroom and grabbed his toothbrush like a sword.
He scrubbed the front teeth, then the back. Toot-toot! Bubbles popped on his tongue.
He spat into the sink and declared, 'No more bugs.'
That night, Leo brushed again with extra vigor, scrubbing every corner.
He rinsed and looked up. His reflection grinned back, teeth sparkling white.
The next morning, Leo brushed without being asked, humming a cheerful tune.
He paused at the mirror, admiring his smile.
Ready to chase any more bugs that showed up.
