Avoid the Green Lake This one is pretty straightforward, we know that as elementals Fireboy can only go on fire and Watergirl can only go in water, but what about the green lake? Both Fireboy and Watergirl have to avoid the green lake. Remember that if one of the characters die you have to restart. Work Together It might be tempting to run ahead with one character and try to finish the level with them before you go to the other, but there are many levels where this is simply impossible. Some levels have switches and buttons that require you to use both characters to get through. Make sure to use both Fireboy and Watergirl in tandem to help you beat each level.
