How to change materials Emmission intensity when there is no Renderer

I have a object which has a Animator, but no Renderer,

I want to make the critter pulse glow, so I need to change the Emission intensity of its texture...how can I do this in a script?

Imagine in standalone shooter tutorial, the Player needed to be able to have its materials emission intensity varied randomly...

Remember, there is NO RENDERER, only a ANIMATOR Thanks!
