Use double spring ball jumps to reach the top-right of the room with temporary blue. To cross the two gaps at the top of the room to the left while chaining temporary blue, use spring ball jumps with HiJump disabled; in each case, perform a stationary lateral mid-air morph or a spring fling (or both);
