From the lower-left floor, use the sloping bottom corner to jump onto the shelf with the low blue diamond. Walk up its right slope, then jump left onto the white plate shelf. Jump for the second blue diamond above the plate and settle on white.
Jump right from white into the fan column. Stay near its middle until Watergirl rises above the upper side shelf, then steer left onto that shelf. Jump right onto the highest roof and walk right through the purple crystal. She emerges on the outer side of the right roof. Wait there.
Fireboy climbs the mirrored lower-right stairs, collecting the low red diamond and the red diamond above the right white plate. Jump left from white into the fan, ride high enough to steer right onto the upper side shelf, then jump left onto the highest roof. Walk left through purple to reach the outer-left roof.
Fireboy walks left off the roof for the upper red diamond, then steps off the right edge of the little side shelf to fall through the next red diamond and land on the white plate shelf. Watergirl mirrors this on the right, collecting both blue diamonds before landing beside the right white plate.
Fireboy activates left white again and repeats the fan climb. On the highest roof, stop just left of purple. Approach with small taps and stop as soon as he appears at the right crystal. While still touching the receiving crystal, turn left through it into the inner-right roof. Continue left past the red door for the high red diamond, then return to the flat part of the roof. This is an intermediate door visit; the room continues while Watergirl is elsewhere.
Watergirl repeats the right white-plate fan climb. Wait on white for a strong fan pulse if needed. Stop just right of purple, approach with small left taps, and stop immediately after appearing at the left crystal. Turn right while still touching that crystal to enter the inner-left roof. Cross the blue door to collect the high blue diamond and return to the flat roof. This intermediate visit also leaves the room playing.
Fireboy walks right through the right purple crystal and continues right from the left crystal onto the inner-left roof. Watergirl walks left through the left crystal and continues left from the right crystal onto the inner-right roof. Both cross their own doors once more while trading roofs, then leave those door areas. Their remaining inner diamonds now match their sides.
Fireboy steps off the right edge of the top-left roof onto the broad sloping shelf below. Walk left off that shelf into the orange crystal shaft to collect its red diamond. As he falls, steer right against the wall so he enters the side opening and lands on the middle ledge. Jump straight up before steering right onto the orange plate, collecting the red diamond above the ledge.
Watergirl mirrors this route: step off the left edge of the top-right roof, walk right into the blue crystal shaft for its blue diamond, then steer left while falling to catch the middle ledge. Jump upward before steering left onto the blue plate and collect the blue diamond above the ledge.
Fireboy leaves orange to the left, landing on the middle ledge. Step right to the central ledge below, then move left off its sloping edge to reach the lower shelf. Follow that shelf’s slope right, collecting the low inner red diamond on the way to the lava floor.
Watergirl leaves blue to the right, lands on the middle ledge, then steps left onto the central ledge below. Move right off its sloping edge and follow the lower shelf left, collecting the low inner blue diamond before reaching the water floor. All sixteen diamonds are now collected.
From the left end of her pool, jump upward before steering right onto the lower shelf. Walk to its flat right end, jump left toward the central sloping ledge, and climb to its flat end. Jump right onto the middle ledge, settle clear of the overhead plate, then jump upward before steering left onto blue.
Leave blue and walk continuously right across the middle ledge into the crystal shaft. Fall through the lower blue crystal while the timer is active. It sends Watergirl upward from the upper blue crystal. Stay in the shaft until above the broad upper shelf, then steer left onto it. Walk up its left slope and jump right onto the highest roof. Wait on the inner side of the right purple crystal.
From the right end of his pool, jump upward before steering left onto the lower shelf. Walk to its flat left end, jump right toward the central ledge, and walk to its flat end. Jump left onto the middle ledge and settle away from the overhead plate. Jump upward before steering right onto orange.
Leave orange and walk continuously left across the middle ledge into its shaft. Fall into the lower orange crystal before its timer ends. Rise from the upper crystal, then steer right onto the broad upper shelf. Climb its right slope and jump left onto the highest roof. Wait on the inner side of the left purple crystal.
Fireboy walks left through purple and continues left from the right crystal to the red door. Watergirl walks right through purple and continues right from the left crystal to the blue door. Either can arrive first; the other waits safely on the opposite roof until ready.
