花之城堡
Flower Castle is an area of the Flower Kingdom in Chapter 5 of Deltarune, following the Cliffs area.
Upon entering Flower Castle, Asgore appears and pushes Kris and Susie back into the Light World while Ralsei hides in a bush. Upon reentering the Dark World, Kris and Susie are imprisoned by Flowery. Aqua somehow teleports into the jail cell, and Seth frees the three in exchange for one of Berdly's feathers. Ralsei pacifies the prison guards and the party enters the foyer through a trapdoor. They then can proceed to the East and West wings.
In the west wing of the castle, Yellow gives the party a key. After being tricked into believing that he trampled on his own flowers he goes through the yellow door to punish himself for failing to display justice. The party tries to stop him, collecting evidence along the way, culminating in the destruction of a laser. Blue gives the party his key shortly after, commenting on the features of Yellow's trail of destruction alongside the party as they descend. After the party is targeted in a misunderstanding, Blue and Yellow challenge the party to prove their innocence of four crimes using a courtroom-based battle format. The last of these crimes turns out to be Blue stealing petals from Yellow, which he uses to make a bouquet for him.
In the east wing of the castle, Orange boasts about her strength, but has little effect on the party; additionally, she ruins Aqua and Seth's otherwise unbeatable bullet pattern. The party finds three Netskies by another Netskie disguised as Aqua in order to progress, and Orange battles them with help from Green.
During all of this, Asgore talks about his plans to look through documents, prove the existence of the Dark Worlds, and get revenge for an unspecified event. The documents that Asgore is looking through fall down to an area accessible by the party. On inspection, they reveal the existence of a Dark World long ago and flavor text about the BlackShard.
Ultimately, both wings end in a scissor, which cuts the bush blocking a screen. The party uses the giant watering can behind it to grow a huge stalk, which leads up to the top of the castle.
The castle comprises an east and west wing, each of which culminate in a fight against two of the flowers. There is also a central atrium, with a hedge to the north blocking the path that can only be cut with scissors at the end of the two wings. The east wing features the Flower Cafe and puzzles regarding shadow, while the west wing features two locked doors, many platforming sections, and a focus on collecting evidence.
The castle's architecture is highly reminiscent of that of various periods of Japanese history. Though mostly taking place inside, there are some alleyways that lead outside. Many of the castle's rooms are unusually large; in particular, most have very high ceilings.
