Riley's eyes shot open and a smile broke out on her face as an idea popped into mind. She had to fight the urge to jump up to her feet. Still, she kept composed and slowly closed her hands around her sister before sitting up.
"I got an idea," Riley said into her hand, still beaming.
"Oh no," Penny mumbled under her breath. She recognized that tone. Nothing good came from that tone. Even if it wasn't as painful or dangerous as Audrey's brand of fun, Riley's shenanigans were almost always embarrassing or humiliating in the worst ways.
Placing Penny on the bedside drawer, Riley dug around in her backpack, pulling out a handful of items.
"Okay, I'm gonna let you pick what we're going to test, okay Pen?" Riley placed the objects onto the drawer next to Penny before growing them to their normal sizes. She gestured to a pair of sandals. "Okay starting off, this is—"

"Oh, okay," Penny said, her voice picking up at the different object.
"My mechanic friend helped me rig a Hot Wheels car with a remote control set up from another toy car." Riley put her finger on top of the toy car and pushed it back and forth idly. "Then we added an actual interior to make sure it was rideable. Now I need a test passenger to make sure it all works together. So! What'll it be?"
Penny swallowed a wad of spit that had been welling up in her mouth. Her gut twisted as she realized that she was going to be strapped in one of these death traps. Still, she had to pick one, so she went with...
