Earth Release: Crocodile Jaw

The user forms hand signs and flows chakra through his feet towards the enemy. Almost immediately the ground in front of and behind the enemy grows dozens of spikes one foot long. The ground proceeds to rise immediately from the front and behind, trapping the opponent in the middle of two slabs of earth filled with spikes, mimicking the motion of a crocodile's jaw shutting. The opponent is immediately impaled by the spikes and killed instantly. However since the attack comes only from behind and the front, a quick witted opponent can escape from the sides.
