Dirty Dancing

You become the master of the earth dance.  For the duration as long as you and your allies dance within 300 feet of the corner you selected for the baby doll, and you dance, you may burrow as an additional movement.  While moving through this medium all have blind sense and acid imunity.  Also as the caster you can deny any creature that already has burrowing from doing such such movement and you may remove blind sense/sight and acid imunity from such creatures.  If a creature was burrowing while within the spells range the caster may use a standard action or a reaction to move one creature to the surface, apply the spell denials and stun them until the end of the casters next turn.
