Entangle IN RATS!!!!!!

Rats emerge from the ground in a 10-foot square within range. For the duration, these rats turn the ground in the area into Difficult Terrain. They disperse when the spell ends.

Each creature (other than you) in the area when you cast the spell must succeed on a Strength saving throw or have the Restrained condition until the spell ends. A Restrained creature can take an action to make a Strength (Athletics) check against your spell save DC. On a success, it frees itself from the grasping plants and is no longer Restrained by them. Any creature restrained by the rats at the end of their turn takes 1d6 piercing damage. 

The rats have a total HP of 20 and can be killed or willed to move as a bonus action by the user.
