With Plasma and a pause abuse, it is possible to kill the Kago and exit G-mode while killing the Kago bugs and make it to the door with a small amount of Energy remaining. Shoot Plasma and quickly exit G-Mode, so that the bugs die immediately. Avoid having spent much time on the left side of the room, as the Fune fireballs will reduce the number of drops obtained. Note that it is possible to climb the left side of the room with SpeedBooster alone, with either a tricky dash jump or a vertical shinespark.

Dev note: All of these methods are fast enough to be able to escape after obtaining the drops. The shinespark is longer than 1 frame, but is modeled this way because the drops aren't properly modeled.
