515 route: Press the blue button (collecting 1 chip en route), then get the 4 chips in the pink ball area (top first). Now go past the tank, push the block R (leave behind the chip immediately above it), then get the chips and suction boots from the maze. Come back and push the block D 2L. Go round the fireball cloner to the force floors, collect the chips and walk down the recessed wall path. Teleport 3 times (all rooms contain fireballs that are in sync), go round the invisible walls to collect 2 chips, then press the green button and push the blocks so that all 3 trap buttons are covered. Teleport twice to return to the start, collect the last 2 chips, press the blue button, go across the traps to push the block U, then go past the tank (the positioning of the block earlier makes this possible) to push the other block U, stopping the pink ball from cloning any more fireballs. Now get the yellow key, press the blue button, get the fire boots, then push the block across the water and walk down to the exit.
