Answer her.

"I'm Steven." Oh. So that's your name?

"Hi, Steven." She gives you a little wave, her arm flattening out and fingers merging together with the momentum, "I'm Slime. You're new here?"

"Yeah. I'm not really sure where 'here' is either."

"It's the Island. I've been here a few months, so don't worry, I can help you get settled." She seems a bit familiar with your situation. Are there others like you?

"Okay. Then uh...what are you?"

"I'm a slime."

Right...

"Slime girl. I dunno. Oh! But I was a human before." You have a feeling there was something else she wasn't saying.
