Bring Fireboy to the orange exit in the upper left and Watergirl to the blue exit in the lower left. Both heroes must be at their own doors together. The 12 unmarked diamonds are optional; collect every diamond for a perfect clear.

Take one hero around while the other waits safely at the start. Fireboy uses the bottom purple crystal to reach the top. Watergirl starts there. Use the purple pair again when needed to emerge on its right side, then collect the matching diamond beside the upper blue pool. Fireboy must jump over that pool.
Continue right along the upper corridor and drop into the green crystal between the two stone ledges. Its partner turns the fall upward. Fireboy collects the red diamond between the two crystals. Move onto the right or left stone ledge to leave the pair, then follow the middle passage left. Watergirl collects the blue diamond under the raised right-hand ledge; Fireboy jumps onto the small middle shelves for his red diamond.
Continue left toward the white crystal beneath the upper-left platform. Fireboy collects the red diamond above it. The white pair connects this opening with the gap in the long middle walkway. Watergirl uses it to collect the blue diamond in the left shaft, then returns through the pair to emerge below the middle walkway. Enter from the appropriate side and move clear of the receiving crystal before turning back.
Collect the red and blue diamonds beside the purple pool by jumping across it; neither hero can touch that pool. Follow the stone steps to the right. Fireboy jumps across to the raised moving platform for the red diamond above it, then descends toward the lower corridor. Watergirl descends the right-hand steps for the blue diamond near their base.
Watergirl can walk through the bottom blue pool to the timed plate on its right bank. Hold it until the moving platform above has lowered, then return left. The platform stays lowered briefly after the plate is released and rises back to its original height. Fireboy must jump over this blue pool whenever crossing the same lower passage.
Watergirl collects the blue diamond above the lower-left shelf before returning to the bottom corridor and her door. If the purple crystal sends her to the top, move clear and enter it from the opposite side to return on its left. Fireboy approaches the bottom purple crystal from the right to emerge on the upper-left side, then walks left to his door. Finish after collecting all six diamonds of each element.

The diamonds in this room are optional. If you only want to finish, bring both heroes fully inside their own matching doors.
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.

2 blue water pools (upper center and lower right) and 1 purple goo pool (lower center). 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.
