All the assets are ready to use in Blender. 

If you want to use it in Unity3d you have to put all the textures in the material slots (like normal textures). I don't have a texture for each slot. But were I didn't textures you should be able to use the values in the shader. 

If you want to make the stuffed animals more realistic you should make a simple velvet shader in Unity. the only thing that would be different to the standard shader would be that you add more fresnel. 

If you have any more question don't hesitate to contact me
