What each input controls
You only need to complete one matching verse.

| Side wheels | Sword | Rotate the plates into the displayed symbol. |
| Colored orb | Place on the center pedestal | Use the color matching the selected light and verse. |
Before that puzzle
The earlier gate needs three levers in the surrounding elevated areas. In the flame-geyser room, break the ladder rubble with Dynamite, cross the towers with Rocket Boots, cut the hanging box’s rope and push it over the flame.
After the gate
Continue to Mount Red Sun. Captain Trotter and The Ancients are ahead; the river puzzle itself does not award Firebrand.
