"I got a tre-" A plant like substance wrapped itself around both of his ankles and pulled him under. After he was under he saw it was a merperson controling some weird type of seaweed. It said "Give me back my tresure and you may live." "No I can't. Now get off." Nate pointed his wand at the seaweed and said "Stupefy." Unfortunately he had to drop the chest, which allowed the merperson to get it. Now he had to deal with a merperson. Oh this was not going to be a pretty site.
