A green-skinned big-headed alien in swimming trunks emerges from the water.

Maurice shrieks and kicks it a bit.

Sadde giggles and makes the alien dive into the water.

Through the simple application of hard light buckets, Maurice drenches Sadde.

Not that this changes much from his current state but alright Sadde can just make more snow appear above Maurice.

He proceeds to trap Sadde in a cube.

A copy of Sadde appears behind Maurice and says, "I hope you remember I need to breathe."

He grins and pokes some air holes in the cube.

The copy vanishes. "It was just an alien!"

And now there's a tentacle wrapping itself around Maurice's ankles and pulling him under then letting him go.

And then flying saucer starts firing upon Sadde. 

Good thing there's a cube around him to protect him from it!

The bolts somehow figure out how to get through the airholes. 

So Sadde makes a tinker-tech based forcfield generator.

"You can make force fields?" says Maurice, shocked.

"I can make things that make forcefields!"

Maurice's amplified voice echoes across the water. "Guys, come look at what Sadde made!"

Okay.

The others amass around Sadde's invention.

"So, you just made this? Your power isn't making it work?"

"Could I borrow it?"

"What do you mean? My power's making it work."

Evan takes a deep breath. "Is this real?"

"Of course."

"Is it only working because you made it?"

"What do you mean?"
