Your walking though Drainage System. It was recently raining so water didn't came down yet. Suddenly, you see something coming up in the water.

"HI THERE!!! Nice to meet youuu!!!"

The head of a blue slugcat showed up. He has wide magenta eyes and pink gills on his cheeks, they look like axolotls gills. The water slowly came down and he jumped on the ground.

"I'm Rivulet! What's your name?"

He looks very friendly.
