biped and mouse.

as you can see in this image the biped is covering the mouse's head this is because of the mouses ears and whiskers as then needed to move with the biped. once that is done you need to connect the biped to the mesh, so unfreeze the mouse and click in the modifier tree and select physic then select ----- the pres H and select pelvis then click OK and then ------ and this will connect the two together. once this has been done you will then need to use the envelopes in changing the strength and radios of the envelopes
