Her expression brightens. "Oh, so you're the good kind of human!"

"...there's a bad kind?"

"The kind that forget things, that take a long time to learn something, that get tired fast, that are clumsy, that do that thing where their body starts falling apart after they finish growing. Michael says it's mean to call them the bad kind."

"Well. I'm that kind."

"Oh, sorry about that. Then how did you turn into a boy? Is it a costume?" She says the last word like it's a  foreign concept to her.

"No, it's a power."

"...But you said you were the less-cool kind of human."

"Yep."

"Did a cool-human do it for you? Because that would be weird magic."

"Nope."

"Ah, so you're like a broken cool-human."

"He's an alien."

Sadde whistles the X-Files theme song.

"...Is that Irish?"

Nemo thinks it sound vaguely like a human trying to speak her tribe's tongue, poorly. 

"So you have the magic of turning into a boy?"

"And making things appear."

"Show me! Show me! Is that why you're sitting in a fake birdie?"

"I can't swim, so I made the duck." He pats the duck.

"Can't swim? Is that like not walking? I'm sorry. And are ducks a kind of bird?"

"Ducks are a kind of bird, and no it's not like not walking because I don't live in the water. Or, well, it's like you not walking."

"Can you still show me your powers?"

"That would be pretty cool."

A beach ball suddenly emerges from the water as if it had floated up from about ten feet down, with quite a lot of acceleration and noise.

The other children are all appropriately startled and impressed. Nemo launches herself on top of the beach ball, revealing the dolphin like fluke that makes up her lower body.

Sadde giggles and makes five more beach balls appear in arbitrary locations around them, all different colors.
