(I think you meant Coral as he's the one who has been splatted by the Steel Eel, Kelp just got scared at the sight of the Steel Eel coming up behind Coral.)
Coral says "Thanks, that Steel Eel managed to somehow sneak up behind me when I turned around looking for any other Salmonids who have the possession of Golden Eggs.", as he thanked Vin for the revival, Coral turned to the Steel Eel and decided it's time for a little payback. He swam up a wall to wait until the driver of the Steel Eel is exposed, conveniently, the Steel Eel started chasing Kelp, not only she was scared, but the situation escalates her status to terrified, losing focus of the battle.
