LoL alright so the mission was to either build a umbrella/ chair set up on the beach or do some coral reservation i believe thats what it was called. So for the corals, they had to build a PVC frag holder and put a bunch of sps frags onto the holder in the ocean. many couldn't do it because the current was too strong for an amateur swimmer and of course 2 contestants are surf boarders and they did it easily. end of story lol basically something like this : http://www.youtube.com/watch?v=yLAZDTUUSdE&list=FLPlx8rEhnJSsmH3EMlBzeJA&index=8
