Custom Rig Mob Problems

I am trying to make a rat boss and it’s my first time making a custom r6 rig, I have a few problems i am now encountering as I am working towards it, the animations partially work and what i mean by that is the Torso doesn’t animate if the humanoidrootpart is unanchored but if it is anchored it cannot move and for some reason if i anchor the root part the torso will now be animated. how can i fix it so i can have it animate unanchored so it can also move?
