From left side, Wait for Shaktool to loop around to the ceiling. Crystal Flash, shinecharge, and jump into the path of Shaktool's rear wheel to interrupt. Or, farm Shaktool with a timed Shinespark: start a diagonal spark from the ground just as Shaktool's back wheel leaves the ceiling, and Shaktool will spawn five drops. Shinecharge again, and use a Yard to interrupt. If Samus came in from the right and can't free Shaktool, there are only the two Yards to work with. Kill a Yard by angering with a shot and then running through it with speed.
