As Sarah looked at the map, she said "It's almost like it appeared right when I wanted it."
"You can't just wish stuff up," Lizzy said.
"Hey, maybe that's how the pool got here," Seth suggested.
"What do you mean?" Lizzy asked.
"You're the one that said you wished you had water. And then shortly after, the pool appeared."
"I didn't say I wanted a swimming pool. Just some water."
"But what were you thinking of, when you said it?" Jeremy asked, seeing where Seth was heading with this.
"Okay, okay. So I was thinking of a pool. But only for a second."
"Maybe that was enough," Jeremy said.
"Enough for what?" Lizzy asked.
"I don't know how it's possible, but I don't think this is any ordinary desert," Jeremy said.
"Of course it's not. It's on an alien world," Lizzy said.
"If it's an alien world, then why is there a swimming pool here?" Seth asked.
"Well ... uh ... I don't know." Lizzy sighed, then turned towards Jeremy. "What do you think is going on?"
"I know this sounds strange, but it fits the evidence," Jeremy said. "I think this desert is one giant canvas. And anything we want can be manifested here."
"That's ridiculous," Lizzy said.
"Oh, really? Watch this," Jeremy said, before dreaming something up.
