Only the lowest three Rippers that are above the right door need to be killed. The highest of the three can barely be reached with a Super and HiJump. Or a PB placed slightly higher than a standard max jump, done by jumping from the door ledge, from an IBJ while avoiding the Ripper, or using 2 PBs.
