Gain a shinecharge by running right-to-left on the underwater runway on the right side of the room. Use HiJump or a Spring Ball jump to quickly exit the water to the left and spark up.

Dev note: FIXME: It's technically possible to evade the Owtches without killing them, but it's unclear if this can be done reliably. A 2->5 shinespark strat from here can also be added, using less energy than the existing strat that uses the runway at the bottom of the room.
