Is it possible to store a game's level-specific functions in one game object and have my animation events reference those functions?

I'm specifically using EX2D which lets me type in my method name for my animation event and I was wondering if I would have to put the specific functions on one script, and place that script on every object to be able to use it or if I could just have one gameObject that gets automatically called via an animation event.

My example would be that I want a sprite object to add to a global variable and spawn a particle with cooresponding number above the tapped game object.

I have code to do this on the gameObject's script and it works fine but the function is so specific to this one stage that it feels sloppy. I imagine I'm missing some huge revelation on how C# works.

I'm not asking for anyone to write the code for me but at least a point in the right direction would be fantastic. I'll show what I have for my locally-declared function to give you an idea of what I'm doing and I'm certain it'll be great for a laugh.

 public void Count (){
         GameObject.Find ("root").GetComponent <root>().intCount++;
         int intCount = GameObject.Find ("root").GetComponent<root>().intCount;
         playRefSound (GameObject.Find ("root").GetComponent <root>().intCount.ToString ());
         GameObject NumParticle = (GameObject) Instantiate(Resources.Load ("NumberParticle"), gameObject.transform.position + new Vector3(0,40,0),Quaternion.Euler (270,0,0));
         NumParticle.GetComponent<ParticleSystem>().renderer.material.mainTexture = Resources.Load ("Numbers/"+intCount.ToString()) as Texture2D;
         Destroy (NumParticle,10);
     }

So this is on a script called SpriteProperties which is on every tappable sprite. It feels like I should be able to stick this on an empty game object, yet still be able to pass an animation event to it as well as the location of the tapped object for instantiating the particle.

Am I just all kinds of backed up over here? Thanks for your time.
