Kindergarten Kid

"Kindergarten Kid" is the 1st episode of the fourth season in Steven Universe, and is the 104th episode overall.

Synopsis
A monster problem surfaces.

Plot
The Crystal Gems look around the Beta Kindergarten in search for imprisoned Corrupted Gems. Steven points one out, and Garnet, Amethyst, and Pearl poof the one on their side. Pearl expresses how Jasper keeping the corrupted Gems in cages was disturbing to her, but Amethyst points out the similarity to what they are doing with the corrupted gems back at the Crystal Temple. Garnet explains Rose Quartz's method: a Gem is cared for in the stasis of a bubble, so they can't hurt the Crystal Gems or get hurt themselves. Steven and Peridot see a corrupted Gem which acts in a humorously stupid way to Peridot, who exclaims that she can't believe the corrupted Gem used to be a proper Gem.

Garnet calls forward Pearl and Amethyst and tells them to get ready, for this particular corrupted Gem is "flighty." Steven asks Peridot if there are any corrupted Gems like this on Homeworld, to which Peridot responds that there was nothing of the sort. Garnet lets the corrupted Gem out and gets charged by said Gem as a result. Amethyst tries to reel it back with the whip but gets dragged off. Pearl shoots at the corrupted Gem to no success as it runs back to throw Amethyst at her. The corrupted Gem scales the wall up to higher ground and successfully retreats. Peridot laughs at how terrible the trio was at how they got outsmarted by a thing with bestial instincts. Pearl explains how it is harder than it looks, but Garnet suggest in no "play by play" since mistakes can happen, even when Garnet can "see the future."

Amethyst challenges Peridot to see if Peridot can do a better performance. Peridot accepts to help, referring to how she saved Steven and Amethyst from the wrath of Jasper. It will also be a great chance to show off her Ferrokinesis. Steven wants to go with Peridot on her hunt to help the corrupted Gem. After Steven catches up, Peridot asks if he came to bring her back. Steven tells her that he did not, but warns Peridot that it usually takes all of the Crystal Gems to capture a corrupted Gem. Peridot states the problem: the Crystal Gems try to out-brute it. Because of this, Peridot's plan is to outsmart it and considers depending on Steven's experience with the corrupted Gems to form a duo the corrupted Gem has no chance against.

The corrupted Gem returns and runs over Steven and Peridot, who give chase afterward. Steven and Peridot stealthily sneak up on the corrupted Gem that is currently under an Injector. Peridot attempts to use her Ferrokinesis to make this injector fall onto the monster by removing its legs. This does not succeed, as the drill embedded in the sandstone can sustain its weight. Peridot is angry at this and kicks where the legs dropped. As this happens, the wall with the drill begins to crumble. Steven tells Peridot to move out of the way, and Peridot thanks Steven for telling her. She kicks the wall again, and a couple of boulders fall onto her. The corrupted Gem attempts to run away. Steven fights it back with his shield, and the injector falls onto Peridot, making Steven run over, sacrificing the chance to capture the corrupted Gem.

Peridot presents her second "Peri-plan": Peridot has cannibalized the injector to make a rudimentary cannon. The weapon will be used to take out the corrupted Gem from a distance. The corrupted Gem comes on the scene, and Peridot prepares to open fire. However, the cannon delays the shot and, after Peridot bangs the cannon, backfires and crashes Peridot into the wall behind her while being buried by boulders. The corrupted Gem walks up to Steven and then begins to attack them. Afterward, Peridot executes plan C and attempts to use simple physics to capture the corrupted Gem because "relying on the injectors introduced too many complicating variables." This plan involves a giant boulder, and Peridot's plan is to get the corrupted Gem under the boulder to drop it on the corrupted Gem's head. The grandest positive of the plan is that nothing can fall on the duo again. The corrupted Gem approaches behind Steven and Peridot and scares them off the edge and, as a bonus, taps the boulder to let it fall on them. It crushes Peridot and has her roll away. Steven gives chase, and the boulder goes through a loop-de-loop erosion to run over Steven. He shields himself but makes himself do a loop-de-loop and hit Peridot's boulder that does another loop-de-loop until it stops halfway and falls on Peridot once more.

At night, Steven is cooking a marshmallow near the fire. Peridot in the distance celebrates her devised plan, which is a construction of the injector with one side supported by a stack of its legs. Due to it lacking proper support, it crashes, to Peridot's displeasure. Peridot questions if she can master this, but Steven lets her know that even if her "Peri-plans" don't work, they were really funny, and the others Crystal Gem members will think so, too, when they go back. Peridot disagrees, for she strives for victory before going back or forward. She claims to be smarter than the average Peridot and questions how she can fail against a corrupted Gem who relies on bestial instincts, or in her words, a "barely functional, stupid, cloddy dumb-dumb." Steven tells Peridot that they aren't dumb but just think differently. Peridot, checking her Earth vocabulary, then considers herself a monster to prove a point, stating that she slams her face into hard objects and throws her tongue in the air for fun, and asks how that is not dumb in her eyes. It is concluded the corrupted Gem was lucky not to fall for Peridot's plans rather than what Steven interpreted it to be intelligence.

Steven starts to throw marshmallows at Peridot, which infuriates her. Steven answers by letting her know what it is like to be a monster: Pretend that a human is screaming at you in fear, to pretend that an Earth animal is chasing her away from her first hiding spot, to pretend an angry green Gem is trying to poof her, and to let her know this form of endless suffering is the monster's life now. This breaks Peridot into a fury, and she steals the bag of marshmallows to chew on it in a fit of anger, which proves Steven's point. Steven helps recollect Peridot's past experiences and connects the similarities to the corrupted Gem and their perspective on the situation with Steven and Peridot now, concluding it is frustration.

Now daytime, Peridot and Steven hide behind a rock and watch the corrupted Gem shooting its tongues into the air. Beginning plan D, Peridot walks up to the corrupted Gem and starts to "act like a monster." After some time, Peridot kicks the corrupted Gem which triggers it to attack. Steven runs over and tries to convince the corrupted Gem to be bubbled, but is inadvertently knocked away. Peridot continues to wrestle the corrupted Gem until they meet the edge of a cliff and fall off. After the fall, the corrupted Gem has finally poofed, and their Gem is in Peridot's hands as she climbs out of the hole the two made from the fall.

Garnet shows up to Steven's surprise until Garnet says she, Amethyst, and Pearl never left. Amethyst knew the hunt would be funny, and Garnet predicted with her future vision. Peridot showed them she could do it, but admits the task being harder than expected and respects the adversary worthy of her skill. She unintentionally bubbles the Gem and wonders what she should do with it, which Steven suggests tapping the top, sending it "home." The bubble appears inside the barn while Lapis Lazuli was reading a book called Pretty Hairstylist. She notices, but does not care and goes back to reading.

Trivia

 * Peridot bubbles a gem for the first time in this episode.
 * Peridot's bubbles are shown to be lime green.
 * It's also shown that Gem Bubbles are sent to wherever the Gem that made it considers to be home. For the Crystal Gems, that's the Crystal Temple. For Peridot, it's The Barn.
 * Peridot reveals that her gem type is extremely resilient to physical trauma and hard to poof (however, she was poofed with ease by Garnet in "Catch and Release", causing a possible continuity error but it can also be that Garnet's stronger ).
 * Her hardness is likely because Peridots are in 6.5 - 7 in Mohs scale of hardness.
 * Garnet could have easily poofed Peridot due to Garnet's being a 6.5 - 7.5 in Mohs scale
 * However, this could imply that Garnet is stronger than what has been shown.
 * Strictly speaking, since Garnet is a nearly-perpetual fusion, it was a simple case of "two against one".
 * This is the second episode to use the Beta Kindergarten as the title card, the first being "Earthlings."
 * This is the third episode where Steven is not present in the ending scene, the first being "Monster Buddies" and the second being "An Indirect Kiss".

Cultural References

 * This episode is most likely parodying the Looney Tunes cartoons staring "Wile E. Coyote and The Road Runner". There are many similarities, including:
 * The desert environment.
 * Peridot and Steven trying to outsmart the corrupted Gem, but always fail to as the corrupted Gem runs away.
 * Peridot falling off of cliffs and getting crushed by boulders.
 * The design of the corrupted gem and her behaviors also seem to be a reference to The Road Runner, with blue fur, long avian legs, the ability to run fast, and a habit of making guttural noises using her tongue (synonymous with the Road Runner's "Meep Meep" catchphrase).
 * Peridot constructs an elaborate device to catch the Gem, only to have it backfire at the moment of truth.
 * In one scene, Peridot wrestles the corrupted Gem and, in the end, falls off a cliff with the corrupted Gem in a similar way the Coyote does.
 * When they hit the ground, a donut-shaped cloud appears.
 * The spot where she fell forms a hole shaped like her and the corrupted gem's body.
 * The animators employed a fade-to-black transition between scenes imitating the Looney Tunes style.
 * When Peridot is pinned under the boulder with only her legs visible, this could be a reference to the Wicked Witch of the East's iconic scene from The Wizard of Oz when the witch gets crushed by Dorothy's house, leaving only her legs seen.
 * The "roar" sound effect used for the Corrupted Gem bubbled by Garnet, Amethyst and Pearl at the beginning of the episode is originally from the Varactyl, a reptilian creature from the Star Wars universe. A modified version of the same sound effect was used for the Pokémon, Palkia, in the Pokémon movies.
 * When Peridot says, "I'm smarter than your average Peridot", this could be a reference to, "I'm smarter than the average bear," commonly referenced from Yogi Bear.
 * The book Lapis Lazuli was reading, Pretty Hairstylist, is most likely a reference to the Pretty Cure anime and manga series.
 * Steven mentioning about endless suffering is based from Siddharta Gautama or Buddha's "Four Noble Truths of Buddhism", more specifically, the first noble truth stated by Buddha given that "man's suffering is indeed endless and inevitable" or "Dukkha".

Continuity

 * This episode follows up on the plot of Jasper's corrupted gem army that she imprisoned in the Beta Kindergarten, which was left abandoned after Jasper's corruption and poofing.
 * The book Lapis was reading, Pretty Hairstylist Volume 3, was seen being read by Amethyst in the episodes, "Keeping It Together" and "Crack the Whip".

Errors

 * When Peridot is trapped under the rolling boulder, her mouth is closed while she screams.
 * When Peridot is about to squat down, her right shoulder strap and yellow diamond are her skin color for one frame.
 * When Steven walks towards Peridot after she forms a bubble, he walks on a depression made by Peridot and the Corrupted Gem without falling.
 * When Peridot and Steven fall off the edge, the diamond symbol on Peridot's clothing is on the back of her collar.
 * When the Corrupted Gem pounces on Peridot after she kicked her, Peridot's gem is missing for a single frame.
 * When Garnet says "Future Vision" Her middle eye is the wrong color.
