Since fire and water don't mix, be sure to not let Fireboy go in the water lakes and don't let Watergirl go in the fire lakes... And keep them both out of the black lakes. Collect diamonds and solve platform puzzles in Fireboy and Watergirl 4! The elemental characters are back for more mystifying action. You can hold buttons and flip levers to activate platforms and open doors. Remember.
