Funky Portal

The Funky Portal is a block introduced in Java Edition 20w14∞ which allows entry into randomly generated dimensions. It is a colored variant of the nether portal block with the color being determined by the destination dimension.

Obtaining
The funky portal block cannot be obtained as an item even by using the command. The funky portal block can be placed using commands such as or  and is generated when throwing a book into a nether portal. Using will set the block and give it randomized block data as to its destination dimension.

Breaking
Funky portal blocks cannot be broken by tools except in creative mode, but can be destroyed by breaking the portal frame, by explosions, or by placing a liquid inside the portal.

Usage
If any book, whether obtained from the Box of Infinite Books or written by a player, is thrown into a nether portal, the portal blocks will change to be funky portal blocks. Entering this new portal will teleport the player into a new, randomized dimension, unless the text leads to an Easter Egg dimension.

After throwing the book into the portal, the book is destroyed. It will not go through the portal after having changed it. Each book generates its own dimension, and books with the same page content generate the same dimension.

Running on funky portal blocks returns the data that includes the name of the dimension. Portals for the same dimension have the same color. Rarely, throwing the book into the portal, the nether portal turns into multiple funky portal colors.
