How to add custom snake textures and skins in a Snake Game?

Hi everyone,
I am working on a Snake-style game and I want to improve the visual design of the snake by adding custom textures or skins.

I have these specific questions:

  1. How should I design and apply textures so the snake body segments look seamless when moving or growing?
  2. How can I set up different skins or materials for the snake (e.g., glowing neon, cartoon stripes, realistic scales)?
  3. What is the best workflow to make the snake’s skin visually change dynamically (like when eating, leveling up, or power-ups)?

Any examples, tutorials, or best practices would help a lot. I am using Unity (or specify your engine).

Thank you!
