Neptune

   Down in the basement of the mansion guesthouse lurks the sharks. This area was recently declared off limits to the Umbrella scientists after the shark specimens broke out of the huge tank they were in. There are 3 sharks all together and now the largest of the 3 which is a massive great white code named FI-3 Neptune lurks beneath with the two medium sized sharks. You have to drain the water in the control room before killing these sharks. You really don't need to kill them as when the water drains they die anyway. The sharks will grab you by the leg and pull you under with them.
