Sorry, no videos.
I don't even know what you're asking me, to be honest.
The "frozen animation"? There is no frozen animation! There's a frozen character effect found in the "frozen effect" folder, alongside a simple guide that explains how to use it.
The "ground and weather effects"? What are those? I have no idea what you mean!
Look for tutorials for your game engine. How to animate a sprite in Unity, or whatever. I can't help you code, unfortunately.
