Normalized movement through the room can be used to manipulate the Sm. Dessgeegas and do this strat reliably without heat protection. The following is one way to do this; other approaches may also be possible. Before entering the room, damage down to between 127 and 159 energy, and unequip Speed Booster if it is collected. Position one pixel away from the door in the previous room. Hold angle-down (and optionally dash), enter the door transition, then hold shot while continuing to hold forward, angle-down, and dash. The shot block will be destroyed by the buffered shot. Continue holding right and dash to run under both Sm. Dessgeegas. After running under the second one, stop for a moment to prevent it from scrolling off camera. Morph, roll all the way against the right wall and quickly lay a Power Bomb. Move slightly to the left to avoid being bounced by the Power Bomb explosion. As the Sm. Dessgeega approaches, roll under it to the left to avoid being hit. Roll back to the right to collect its Power Bomb drop (which should be a ground level) and return to where the Power Bomb was laid, in time to perform the Crystal Flash inputs.

A normalized entrance to the room can be used to manipulate the Sm. Dessgeegas and do this strat reliably without heat protection.

Position one pixel away from the door in the previous room. Enter the door transition (with or without holding dash), then hold dash and left until falling off the platform. Turn around and hold right, landing in the corner. Morph and lay a Power Bomb. Move slightly to the left to avoid being bounced by the Power Bomb explosion. As the Sm. Dessgeega approaches, roll under it to the left to avoid being hit.
