Beta Kindergarten

The Beta Kindergarten is an abandoned Kindergarten facility located on Earth in Facet Nine. This site was established half way through the Rebellion in order to quickly create more soldiers on the ground. It was first mentioned in "It Could've Been Great" and first appeared in "Beta".

Peridot shows Amethyst and Steven the Beta Kindergarten to cheer up Amethyst since the Beta Kindergarten is poorly made and thought out. They soon get to Jasper's Hole there, and it is revealed that Jasper was the only successful quartz made there. They soon encounter some corrupted gems in cages and find Jasper holding them captive.

The majority of this episode takes place in the Beta Kindergarten. During a fight with Jasper, Amethyst and Steven fuse to form Smoky Quartz. While some corrupted gems escape from their cages, Jasper fuses with one of the corrupted gems, but they are defeated easily by Smoky Quartz. Jasper and the corrupted gem unfuse, and Jasper herself becomes corrupted as the result of her fusion. She is poofed by Peridot, and the group leaves the Kindergarten, returning to the barn.

"Kindergarten Kid"
The Crystal Gems look around the Beta Kindergarten to poof and bubble any leftover Corrupted gems that were locked up by Jasper.After the trio fail to capture the Unknown Corrupted Gem, Peridot laughs at how terrible they were at how they got outsmarted by a thing with bestial instincts. They eventually decide to let Peridot capture the gem herself, but she soon discovers that it's a lot harder than it looks. Many of her "Peri-plans" fail, and she gets frustrated. With the help of Steven, she eventually chases the gem off a cliff, and successfully poofs and bubbles the corrupted gem.
