The Arboretum is a huge platform made from woven branches. It is surrounded by tree houses and fruit stands. It is located in the center of the main RainWing village in the Rainforest Kingdom. It's first introduced in The Hidden Kingdom. It seems to be a meeting place for the RainWings and where many public events take place, similar to an amphitheater.
When Glory challenged Queen Magnificent and the other RainWing queens (Queen Exquisite, Queen Grandeur, Queen Fruit Bat, and Queen Dazzling; except for Queen Splendor because she had been captured by the NightWings) for the throne, instead of fighting to the death, they play a series of challenges at the Arboretum; these included a race, a venom-spitting contest, hide-and-seek (with their camouflage), fruit gathering, and a flower hunt.
In Winter Turning, Glory calls all the RainWings to meet in the Arboretum.
- Entering the Arboretum reminded Queen Glory of Queen Scarlet's gladiator arena; it is likely it was chosen for its potential to function as one.
- An arboretum is a piece of land on which trees are grown for display.
