Okay kiddo, have you heard of the Cajun Navy? They are a group of really kind people from Louisiana who like to help others during natural disasters, like hurricanes and floods.
You know how when it rains really hard, sometimes the water can get really high and cover streets and even peoples' homes? Well, during big disasters like this, the Cajun Navy will use their boats to go out and rescue people who are trapped or can't get to safety on their own.
They choose the name "Cajun" because it's a name that represents the people of Louisiana, who are really good at coming together and helping each other out when things get tough.
The Cajun Navy doesn't get paid for their help - they just want to make sure that everyone is safe and taken care of. So next time there's a big storm, you can feel a little better knowing that there are people out there like the Cajun Navy who are working really hard to help others.
