We Need a Sub!

Now that Wood World is safe, we move on to the next planet. So use MAGIPORT to warp back to the spaceboat port, heal at the Inn in Beatle Town, and finally board our ship again. From Wood World, fly west until you reach something that looks like a giant nebula (or in Game Boy terms, a large white spot). From there, fly directly north. Soon, you'll see the next planet, Water World. Land ho!

Ahh.. the vast sea... From the Spaceboat Port, travel east until you reach a straw hut. Talk to the Merman there to learn of a city beneath the waves called Flotown. We need a submarine to get down there, so guess where we have to fly back to again? That's right! Dr. Justice! Fly back to Mecha Colony and he'll build you the Mach Dolphin, a submarine complete with onions, tomatoes, and... never mind, it's not funny..
