Beastly Purple, (or Enda's Grand Castle) is a castle within Enda's Planet located on the cotton candy mountains. It is 1028.3 m (about 3363.8451 feet) tall and houses a slew of different rooms and environments.
Exterior:
The exterior to Beastly Purple is a giant purple castle with different pillars that are 1028.3 meters tall. At the top of the castle there are huge spikes as well as a balcony that Enda could view from. The castle is able to change color by Enda using her rainbow and color manipulation.
The entrance to the main interior consists of a huge staircase that situates towards one of the pillars to the castle. The castle is supported with huge pillars that keep it balanced. The castle was built by Enda in just under ten seconds. All exterior design, all rooms etc.
Interior:
The interior to Beastly Purple is a bit strange. Because there are rooms and doors that lead to complete realms and pocket dimensions, Enda created, the space seems to be quite non-Euclidean. When entering the castle, there's a huge main room with two huge spiral staircases and many pillars that connect to many parts of the castle.
The entrance is an oval shape, and the floor is wide and huge glass that expands through the huge main entrance. Throughout the entrance, doors are placed along huge pillars that extend to the ceiling, with the ceiling sporting a huge chandelier with candles and a purple design.
The main room connects to millions of rooms. There are elevators, staircases and of course doors that open to pocket dimensions such as the cotton candy world, the chocolate marsh, the sugary forest and much more.
Enda's Room:
Enda's room which is located at the top of the tower featuring a balcony. The room is the smallest necessity to the tower that Enda resides in. Before entering the room there are many hallways that lead towards the room, each having curtains that protect candy plants that grow. Enda's room is commonly shown through the series, one particular showcase being chapter one, when she created Voida a candy that was extremely hot.
