"Log date 8 11 5, about half a rotation since my release. I... blew myself up." Peridot blushed a bright green as they perceived the creature to be staring at them. "Don't look at me like that! How was I supposed to know it mattered that the bread frying appliance was still plugged in when I dropped it in the water?"
The centipeedle was still staring at them as the two sat on the counter in the light of the full moon, but the green Gem decided to ignore it.
"Anyways, this was my second regeneration in the span of one Earth rotation. No visible damage to my Gem has been observed, however I will need to take better precaution from now on. Otherwise, progress on the communicator is off to a good start. We have gathered most of the parts we need. I only wish I had a better assistant."
They gave a pointed glare to the creature, which was drooling all over a pile of salvaged parts. "Peridot, Facet 5, end log. What are you doing, you strange creature?"
With a yawn, the creature stood up. It looked over at Peridot with a somewhat bored expression before jumping to the watery ground and wading towards the remains of Steven's bedroom.
The green Gem groaned. "It doesn't matter. I need to get back to work, and this time I won't blow myself up!"
With a winning grin, they leaned over and opened a cupboard on the side of the counter. From there, they drew out two plungers and a full roll of duct tape.
"Nya-haha! I don't know what these human inventions were originally for, but if I tie them to my feet then these isoprene polymers will protect me from any electrical accidents. I'm a genius!"
A loud growl rumbled through the night, causing Peridot to squeak and curl into a foetal position. When they dared look through their hands, all they saw was the centipeedle tearing apart a bag of Chaaaaaps.
With a stream of disgruntled mumbling, Peridot unravelled a section of sticky duct tape with a ripping sound and began sticking the two plungers to their feet. When they were done, they hopped off the counter and, upon seeing that they did not spontaneously combust upon contact with the water, let out a cackling victory celebration.
"Ye-es! Victory is mine!" They tottered into the middle of the kitchen. "Now, the magnetron in this 'microwave' may be useful to me..."
A growling started up, deep and chilling.
"Stop doing that, you idiot creature!" Peridot snapped, not turning around to investigate the noise. They were too busy using a leverage optimiser to remove the screws holding the microwave in place.
The sound did not stop. If anything, it got louder... or closer.
"I said... Nya, why bother? You don't listen anyway, like those Crystal Gems but worse." They loosened the last screw, and the appliance came tumbling into their arms. It was surprisingly heavy.
Peridot turned. "Now will you be-" And then they stopped, and then they gasped, because the creature that had cornered them in the kitchen was not the centipeedle.
For one, it was blue, and almost as tall as the house, its surface shimmering like slightly melted ice in the moonlight. Its face was comprised of three black holes carved into its main body, with short study legs and very long arms. As the little Gem stood there, shaking in terror, it took a deep breath and roared right at them, dusting them with a layer of freezing snow. Then it took a step forward, taloned hands reaching out-
And there it stopped. It stumbled back, letting out a shrill, terrified screech and twisting slightly to the side, revealing the centipeedle latched onto its body. The blue monster swatted at the creature and hit it right on the head, knocking it to the ground with a cry of pain. Before a second had passed however, it shot up with a spitting snarl, its gemstone eye glowing faintly in the shadow. The blue monster confronted it head on, only to get a glob of green acid in the face. Uttering that piercing screech again, it could not stop the centipeedle from leaping and biting into it from the back, ripping out an arm, forcing it with a flurry of violent twists to the floor right in front of Peridot.
Peridot stood there in shock for a moment, their analytical mind struggling to take in the events that had just transpired. The centipeedle was looking straight at them from the middle of their wide-open jaw, making grunting noises as it kept the blue monster pinned to the ground as it thrashed in the thin layer of water. It seemed to want them to do something.
Dumbly, they looked from the scene to the heavy microwave in their hands. Then they released their grip on it, and it smashed right on the back of the blue monster's head, poofing it. A small dark blue Gem plopped into the water, which Peridot took a second to pick up.
"Oh, my stars." The green Gem breathed, before jumping back at the sight of the centipeedle walking towards them with bits of blue entangled in its hair. "Nya! I mean... you saved me?"
They stepped over the microwave, and carefully reached a hand out towards the centipeedle. The creature made a snuffling noise as it approached the hand, its hackles gradually lowering.
Just as Peridot was about to touch the tip of the creature's black snout, an excess glob of green acid trailed down its jaw and landed on one of the plungers they were wearing, dissolving most of the rubber almost instantaneously and only narrowly missing the actual foot. With a startled yelp, Peridot jumped back, tripped over the microwave and smashed their head on the counter.
"Ow!" They rubbed the affected region, and saw the creature was still staring at them from behind the microwave. "You clod, leave me! I will assign you to sentry duty; you will be of more use there than helping me salvage this microwave. And wow thanks!"
With a snort, the centipeedle wandered off to find the next bag of Chaaaaaps.
