How do you get past fire boy and water girl the forest temple second branch to the right green gem level?

To complete the green gem level in Fireboy and Watergirl: The Forest Temple, have Watergirl activate the first switch to open the gate for Fireboy. Then, Fireboy should navigate to collect the green gem while avoiding the lava. Use Watergirl to press the next switch, allowing Fireboy to cross safely. Finally, both characters must work together to reach the exit door.
