Sea Exploring

The next morning, Sonic dressed up in scuba gear and prepared to meet up Amy at the beach again.

"Where could she be at?" Sonic wondered.
"Over here!" Called Amy. Sonic turns around and sees her laying on a rock.
"There you are Amy" Sonic saw her.

"Yes here I am. Ready to see the unseen world with me?" Amy asked and got off the rock.
"Ready as I'll ever be" Sonic jumps into the water.

Once underwater, Amy was showing Sonic around in the reef filled with life.

"My, I never seen a reef filled with so many creatures" Sonic said.
"You like it?" Amy asked.
"Yeah I do. Is there more to see?" Sonic asked.

"Yes, there is" Amy leads Sonic to the underwater city she lived at.
"Wow, is this really a underwater city?" Sonic was amazed at the sight.
"No surface people has seen this before, you're the first" Amy said.

"I guess. But the pressure of the water. My body can't handle 33 feet depth" Sonic said.
"Okay. But lets have a view over the city then" Amy takes Sonic's hand, letting him see the view over the under water city. Sonic saw the bio-luminescence light emerging from the city's bottom, glowing in a bright blue light.

He also noticed some mermobians swimming with some sea creatures like whales or manta rays.

"Impressive, your people is living quite the life" Sonic said.
"Thank you" Amy smiled.
"No problem" Sonic said and they went to Amy's department, which was at the higher spots of the ocean floor.

Once inside, Amy suddenly stops Sonic.

"Wait here" Amy swam into her room. Sonic waited in the living room looking around there. He could see she got a TV in shape of a large clam, some pictures of the wall with friends or family.

"Hmmm who's this?" He picked the one of Amy and Silver.

"That would be Silver, my best friend" Amy said behind him. In her hand she held a necklace.

"This is so you can breathe without oxygen tank" Amy explained and puts it on Sonic.
"You sure?" He asked her uncertain.
"Trust me" Amy takes the scuba mask off Sonic, Sonic holds his breath but then felt like the water was like air for him. He also noticed his legs are now a fish tail.

"I can breathe underwater!" Sonic was surprised.
"I told you Sonic. Lets have some fun" Amy puts the scuba gear aside and swims with Sonic out the house.

As Sonic and Amy went through the underwater city, they soon encounter a lavender mermaid cat.

"Hi Blaze" Amy waved.
"Hi Amy. Who's the guy here?" Blaze saw Sonic.
"I'm Sonic the Hedgehog. I come from the surface world" Sonic said.

"Wow, really?" Blaze was shocked.
"I saved him from drowning" Amy explained. Blaze looked suspicously at Sonic but noticed he still wore the scuba suit shirt on him.
"Well I can tell that shirt is not from our city Aquapolis" Blaze said.
"Aquapolis?"
"Our city Sonic" Amy explained.
"Right of course" Sonic understood.

"If you excuse me guys, I gotta go. See ya" Blaze swam away.
"Now where were we Sonic? Oh yes, sightseeing" Amy said and swam with Sonic some more in the city.
