The Dimensional Tree is a plane of existence where all the green magic in the multiverse interconnects with each reality's version of the Heart of the Forest.
Painballs grow from the tree and detach like fruit once a traumatic memory is made. They then fall through its various layers, and eventually end up in the Undergrowth.
It exists between the dimensions of the Multiverse, and is insinuated by Prismo that other cosmic beings cannot interfere with it.
Description
The Dimensional Tree is a mystical place between the dimensions of the Adventure Time universe. It is a kind of cosmic plane of existence where all the green magic of the multiverse is connected to the different versions of what is called the Heart of the Forest in each reality: a living network that connects the worlds together.
Within this strange structure, fruits called painballs grow on the tree and fall like fruit as soon as a traumatic memory is created. These fruits descend through the different levels of the Dimensional Tree before arriving in an area known as the Undergrowth.
This cosmic place is interstitial: it exists between dimensions, which means that powerful beings like Prismo suggest that even cosmic entities cannot directly interfere with it.
Place
The Dimensional Tree is composed of different levels, such as the Undergrowth, a place. The Enfaître is a plane of existence located beneath the Dimensional Tree. It appears to be composed of several different layers.
