Use the spikes, which are not in the water, to jump from platform to platform as a way to cross the room. Requires knowing the position of every spike in the room, and hitting the spikes while morphed can help. The first jump is particularly tough. A Spring Ball jump from the sand to the spike with HiJump, or a frozen Mochtroid can be used to get past it.
