The Universe kids were running down the boardwalk after school, heading to the Big Donut. Talking excitedly about what they were going to get, and what order to do their homework.
"Come On Robbie, you're so slow! We'll never get those Cookie Cats with you dragging behind" Page yelled.
"Then pick me up, the only one faster than you is Steven, and he's already at Fish Stew, I have little legs and-- Hey Soph, what're you doing?" Robbie answered. Alarmed, he shouts out when his twin grabs his arm.
"Short legs are no excuse, come on!" Sophie shouts back, dragging him faster down the slatted walkway. They caught up to their siblings in no time. Just in time, in fact, to hear the pained yelling of their oldest brother inside the donut shop.

"What do you mean 'discontinued'? Cookie Cats are the best! Why would they stop making them?" Steven questioned the girl behind the counter, Sadie. The rest of the kids murmured their own discontent at the news. Page offhandedly righted the ladder the stocking boy, Lars, was on when it tipped after her sibling ran into it. Sadie offered the kids the little freezer the ice cream sandwiches were displayed in, since they were just going to throw it away. Dejected, the four children walked off towards home with their new gift. 

Arriving home, the kids walked into a chaotic scene. The gems, Bismuth, Amethyst, and Spinel were fighting green and black worm looking monsters, hitting or squeezing them until they poofed.
"Sorry Meatballs, we'll get these centipeedles out of the house as soon as we can" Bismuth said, squishing two of hem between her hammer shaped hands.
"Uh guys, none of these have Gems" Amethyst yelled.
"Then there must be a mother around somewhere" Spinel answered, swinging a giant fist into one trying to climb up Page's leg. She reeled in her arm like a fishing rod, and after a quick look, decided there were no more immediate threats. The childen then unloaded their backpacks onto the kitchen table, Steven putting the small freezer, next to the big one, and reaching for the freezer door to grab snacks for his siblings. 

"Woah, Cookie Cats! Lots of them! I thought they stopped making them?"
"That's what we heard too, Steven" Spinel said.
"So last night we went out and stole a bunch!" Amethyst shouted. She was sitting on the island between the sink and table.
"We didn't steal, I paid for them" Spinel retorted.
"It was my idea" Bismuth finished. 
"Only because you were the one to see Garnet's warning this time." Spinel countered.
Steven and his siblings were barely listening as they each grabbed one of the treats out of the open door and jumped for joy. Spenel correctly mused out loud that the theme song was coming.
"Oohhh! He's a frozen treat with an all new taste" Steven started.
"'Cause he came to this world from outer space" Page continued.
A refugee from an interstellar war" Robbie sang.
"But now he's at your local grocery store" Sophie finished.
Together they sang "Cookie Cat! He's a pet for your tummy! Cookie Cat! He's super duper yummy! Cookie Cat! He left his family behind! Cookiee Caaat!"
"Now available at Gurgen's of Route 109" Steven added at the end, getting chided by Page, as that's not actually part of the song. The children took a bite out of their sandwiches and happy sounds came from each of them.

All at once the kitchen started to be filled with various colors of bright lights as the children's gems all glowed at once, though with the shock they all dimmed out before anything else happened. Spinel gave them all a noodly hug, telling them that it was okay that they couldn't summon anything yet, it was just good that they glowed. A loud sound came from outside and when everyone rushed outside to see, a large Centipeedle loomed outside on the beach. The Gems all summoned or shifted their weapons and headed out to fight, leaving the children behind. 

The Gems had trouble fighting the giant monster, and ended up pinned down behind one of the hands of the temple statue. The children couldn't stand to see their guardians in danger like this so they each headed out with the small freezer full of the treats so that they could try to summon something from their gems. It was all for naught though as the only thing they were able to summon was a tummy ache for each of them. Steven and Page worked together to throw the, now hated, freezer at the enemy and a short occurred that ended up poofing the monster with electricity. With the gem bubbled and in the temple, the makeshift family made it back to the house in time to see Greg pull up. He asked how the day went, and with a recap, only commented on the glowing of his children's gems. he asked if he could see.

The children grabbed the remainder of their first treats, and tried again, to no avail. Page quickly quipped that at least they still had these treats to remember the day, and as the kids took their bites, the gems started to glow this time. A glove appeared on Robbie's hand, immediately squishing his food and tipping him over onto the floor. Pearl's spear came halfway out of Page's forehead, point first, so the poor girl looked like a unicorn. Sophie grimaced in pain and moved her hair out of her eyes, her left one rolling around randomly as the child spouted off random things, new names of gems they didn't know and places they've never been. Steven stood there with Rose's shield hovering in front of him until he noticed it and it went lying around the house, embedding itself in a wall. when every calmed down from the shock, the weapons poofed, and Sophie calmed down, covering her now blind eye back up. Greg sent the kids to wash up for supper, the children looking positively green after eating so many ice cream sandwiches. Greg looked at his adopted sisters in law and made a comment about things changing now. The looks he got from them weren't encouraging.
