Unlike the other homes, this one seems to be oddly shaped like a glass bowl. To your surprise, it is filled with them. There are large bowls, small bowls, bowls that could hardly fit a human pinky...why would anyone in the sea keep fish bowls?
To add to the shock, there is a woman within one of them, stroking a gold fish. When she sees you, she swims out to meet you. You almost run, but she smiles sweetly and greets you with her name, "Sadira".
"What do you...?" you begin, bewildered.
"Oh these?" she says, waving her hands at them. "Those are to help those fish who have moved down here from above the water. Some of them grew up in bowls, making it hard for them to live in the Ocean. So now they're in Aquax."
She still sees that you look confused, so she yells, "Ruddry! Venvan!" Are those names?
Sure enough two gold fish, who had both been in bowls in the corner, swim out to meet you. They don't look very happy with their new surroundings. "You see, Ruddry and Venvan were caught and put in a bowl. So I'm trying to get them to learn how to live here."
"Fish shouldn't be in bowls," you agree.
"Have you been to the library?" she interjects suddenly. "There are lots of interesting things in there...especially one book in particular."
But whichever book it is, you'll have to find it on your own, because Sadira pushes you back out of the house. "Go to the library!" she says again before swimming back in.
