Is the Mushroom Really a Muscle?

We're not only alive and that tries to describe things, i feel like you need a unit. So maybe they's like alien forms stead of all like mushrooms. Oh, why not? They don't need to count discreetly. But for someone like us, and someone like intelligent alien civilization, i can see them needing something like it. What'll a mushroom do? Hey, i'm different. Ok. I'm just going to continue sitting here for the rest of my life. Let me go do something about it."
