A holiday is a time to celebrate. Some holidays are St. Patrick's day, Veteran's Day, Independence Day, and Thanksgiving. A hook is curved. Your lips vibrate when you toot a horn. A hornet is a kind of wasp, a flying, stinging insect.
Horses are very fast runners.
The horseshoe crab is a hard-shelled animal that lives in warm coastal waters on the sea floor. An hourglass measures time as sand falls through a thin opening. Some people live in houses. The Howler Monkey is the loudest monkey in the world. They can hover in the air and even fly backwards.
