Deleting animation scripts

What is the name of the script to delete animation scripts in a prim? For instance: I have a prim but it has a water script runnning inside of it. I want to use that same prim but without the moving animation. I delete the script but it continues to flow but I want to make it stop.

Whats the name of this script and where can I buy it?

Thank You

OK, so you have a particle system embedded in the object? You do not need to buy anything, there are tiny scripts you can copy and paste into the prim to fix this.

There is a list of these here:

To save a few clicks:

default {
    state_entry() {
        llParticleSystem([]);
        llSetTextureAnim(FALSE, ALL_SIDES, 0, 0, 0.0, 0.0, 1.0);
        llRemoveInventory(llGetScriptName());
    }
}
