Okay kiddo, do you know what a snake is? It's a long, slimy animal that slithers around on its belly. Now, a reuben snake is a special kind of snake that looks like a sandwich!
You know how sandwiches have different layers of bread, meat, cheese, and other yummy things? Well, a reuben snake has different layers of scales that are different colors- just like the layers of a sandwich. Some scales might be brown, some might be yellow, and some might be green.
Also, the scales on a reuben snake can change colors depending on mood or temperature. If the snake is feeling happy and warm, it might have bright, colorful scales. But if it's feeling scared or cold, its scales might be dark and bland.
So, while a reuben snake might not be a real animal, it's a fun way to imagine a snake that looks like a delicious sandwich with a lot of cool colors!
