secret worlds: north jungle court
Once you have screw attack, make your way to the top of the room and look for the ledge in the video. If it's the right ledge, the energy generator will be straight ahead when you look at it.
Do a spring-bsj and screw attack to the generator, trying to avoid the bar sticking out. You should hit an invisible wall and land perfectly on top. Space jump forward to go through the wall and enter the secret world.
