Watergirl collects the blue diamond above the lower-left shelves and jumps onto the lowered green lift. Fireboy collects the nearby red diamond and stands on the lower green plate. Keep him there while Watergirl rides up, climbs the left shelves for the next two blue diamonds, and reaches the upper green plate.
Fireboy leaves the lower plate and waits on the fixed shelf to its right. Watergirl steps right off the upper plate so the green lift lowers again. Fireboy jumps onto the lowered lift. Watergirl returns to the upper plate and holds it until he has ridden up and left the lift safely.
Fireboy climbs the left shelves for the two upper red diamonds, then reaches the required neutral diamond beside the top white crystal. If the crystal transfers him down, step clear and enter the lower one again to return. Descend through the middle shelves for the red diamond above the orange pool and the red diamond near the central lower ramp. Finish with the red diamond on the dry bank to the right of the bottom purple pool.
Watergirl can now leave the upper green plate. Descend through the left passages to the lower white crystal and use it to reach the upper-right area. Follow the stone shelves for the blue diamond above the blue pool, the blue diamond beside the middle-left ledge, and the last blue diamond above the lower-right shelf. Finish on the orange plate ledge. All thirteen diamonds should now be collected.
Fireboy jumps left over the bottom purple pool onto its dry bank, climbs the central plinth, and uses the diagonal ramp on its left to jump onto the low arch. Watergirl walks down and left from the orange ledge to the long lower shelf, then jumps left onto that same low arch. Either hero can make this return first.
Watergirl walks across her blue pool and climbs its right-hand slope. Fireboy instead jumps left from the arch’s upper step onto the small wedge by the central wall, then jumps right onto his higher orange-pool shelf. Cross that safe orange pool and drop from its right bank onto the sloping stone beyond the blue pool.
Both heroes climb the right-hand stone slope and jump onto the short ledge by the right wall. Jump left onto the long upper shelf. Continue left across the upper arch, jumping over the purple pool, and climb the short stone ledges beside the central wall. Jump left onto the upper-left roof.
Return right over the upper stone arches. From the high slope beneath the exit shelf, jump onto that shelf’s pointed left lip. Passing through its white crystal transfers the hero to the bottom passage; step clear, re-enter the lower crystal, and emerge on the right side of the top shelf.
Fireboy walks to the red door on the right and Watergirl stops at the blue door beside it. Either hero may complete this return first. Finish with all thirteen diamonds and both doors occupied.

Count the ring-marked diamonds still visible. All 1 are required before both matching doors can finish this room; each hero collects their own color.
A pressure plate releases when its rider or weight leaves. Keep your partner on it until you are safely across. Levers stay set after you leave; check their ON or OFF state before crossing.
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.
