Secret Worlds: Training Chamber (FJ)

Notes:

The video shows this secret world with floaty jump.
With floaty jump: Stand infront of the wave door facing the boostball pit. On either side there is a metal ornament. The base of each ornament makes a small standable ledge. Jump onto either one. From here you can simply jump into the secret world.
Without floaty jump: Face the wave door. There is a small metal pipe above it. Jump onto the pipe. From here you can jump to either of the ledges described above. Near each ornament, you should notice a section of the wall that appears to be lower. About half of each gap is covered by invisible walls, but they are still lower than the rest of the wall. A very precise space jump will allow you to clear either one.
