Sprout Lands - Asset Pack

Great assets! Really liked.

I don't understand why files doesn't follow any name convention. For example, there are files named:

- chicken default

- Free Chicken Sprites

- Chicken_Baby

- Chicken_Animations_GifPreview

I was expecting every file following the same name convention. For example, if they all use "snake_case":

- chicken_default

- free_chicken_sprites

- chicken_baby

- chicken_animations_gif_preview

Also, the premium comes with the free assets too. So I need to use both together? Can't I just use the biggest sprite sheet?

Let's look at the chicken where the premium sprite sheet doesn't seen to include the second image from free sprite sheet (at least, I don't think so).
