Gil heads to Deema's shop in order to get a firefighter helmet. She tells him that he must first help a firefighter with an emergency, then pushes a button to make a small fire pop up on the building behind her. Gil then presses the button to make the water start but nothing happens.
Deema informs him that in order to make water come out, the ladder needs to match the fire's location in height. So Gil has to pick the right ladder, then longest hose in order to reach it. He puts out the fire and Deema gives him the helmet he wanted.
