Shortcharge to kill the Owtch or kill it with Plasma, a Power Bomb, or a Charge shot while it is moving to the left. It is possible to wait for the Owtch to be at the far end of the flat portion to have a bit extra room to get blue speed. Shinespark into the floating platform to get up without using too much Energy.

Dev note: Charge isn't included here, as it's unintuitive enough that killing the Owtch with blue speed will be a bit lower difficulty. Manipulating the Owtch's position is also not expected. This runway assumes a worst-case positioning of the Owtch.
