OK so there would be a few streets of Underwater Glitches. To "breathe" you would have to go to a tool vendor and buy a scuba mask. If you didn't have a scuba mask you would lose 50 energy and 20 mood and be bumped to the surface. There would be osters and algele. You would use your pick to mine an oster and maybe get a pearl(red pearl,blue pearl, silver pearl, and sparkely pearl) worth 1k-20k when sold at a tool vendor. When you got all the pearls you would get a trophy! You would use a glove(bought at tool vendors) topick algeae used in seaweed cakes which can be made in a frying pan.
