Fireboy jumps left for the red diamond beside the green floor crystal, then falls through it to the left middle ledge. Watergirl does the mirror image: jump right for the blue diamond and fall into the orange floor crystal to reach the right middle ledge. Move away from each receiving crystal and collect the nearby matching diamond.
Jump toward the second matching diamond farther inward, then land on the shelf below. Return to the outer wall and enter the yellow crystal to reach the bottom side chamber. Fireboy visits the bottom left; Watergirl visits the bottom right. Jump for the diamond there and leave the nearby blue lever on, using Interact if a return crossing toggles it off. These levers raise the narrow barriers near the upper pools. Stay in the side alcoves, away from the long purple pool.
Return through the same yellow pair. Fireboy leaves the left shelf through the orange floor crystal, reaching the right middle ledge; Watergirl leaves the right shelf through the green floor crystal, reaching the left middle ledge. Jump inward across the small stone supports toward the horizontal crystal in the center, collecting the matching diamond above it.
Fireboy enters the purple horizontal crystal to emerge beside the upper-right red pool. Watergirl uses the white horizontal crystal to emerge beside the upper-left blue pool. These pools match their elements. Collect the diamond near the outer wall, then jump inward for the next matching diamond and return to the side passage.
Use the raised narrow barrier and the nearby stone steps to climb to the highest level. Fireboy jumps over the upper blue pool for the high red diamond; Watergirl jumps over the upper red pool for the high blue diamond. Land on the raised barrier or the safe bank rather than in the opposite element’s pool.
Fireboy continues right to the red door and Watergirl continues left to the blue door. The other hero can wait safely at the original starting shelf until their turn. Finish only after collecting all eight diamonds for each hero.

The diamonds in this room are optional. If you only want to finish, bring both heroes fully inside their own matching doors.
Return to safe ground and use the connected switch to bring it back. Board before your partner releases the plate or changes the lever. Avoid jumping into its underside; line up with the open shaft first.
Pause and choose Restart level to reset both heroes, diamonds, weights, and switches. Previously completed levels stay saved. Follow the step order before moving a box or releasing a weight.

16 diamonds: 8 for Fireboy and 8 for Watergirl. None are required to finish. 16 unmarked diamonds are optional collectibles for a perfect clear.
3 orange lava pools (upper left, middle right, and lower left), 3 blue water pools (upper right, middle left, and lower right), and 1 purple goo pool (lower center). Fireboy can enter orange lava; Watergirl must avoid it. Watergirl can enter blue water; Fireboy must avoid it. Purple goo defeats either hero. If either hero falls into a dangerous pool, both players restart the level.
