how can i create a Chain Chomp like super mario 3?

I've been trying for a long time to create an identical enemy like the Chain Chomp from Super Mario 3 but I don't understand how it behaves. I hope someone gives me an idea of how to create one.Thank you

Chain chomp has a lot going on.

Here's a quick attempt I made, there's still a lot of room for improvement, but the basics are there.

This is the best example I have seen. Thank you very much, you do not know how much you have helped me.

Updated with a couple minor improvements.

by chance you know how mario 3 firesnake works

It's much simpler. Just give it the platform behavior and simulate left/right and jump for the main body. If you can set up the main body then the pieces following it are the exact same thing, with a delay.

Thank you very much I will try. And if one day I finish my game I will include you in the credits
