End Portal Frame

End Portal (End Portal Frame in the Console Editions) is a block. It resembles an End Stone with a decorative bluish-green top, with sides decorated in hollow rounded rectangles with the same color as the top.

Obtaining
Like Bedrock, the end portal blocks are indestructible, except by using creative mode or cheats.

Natural Generation
The End Portal generates naturally in Stronghold portal rooms over a pool of lava with a staircase containing a silverfish spawner. It generates end portal blocks in a 5×5 square border, without the corners. Each end portal block generates facing inwards. End portal blocks may randomly contain an eye of ender when generated.

Each Stronghold only contains one End Portal, and each world only contains three strongholds, so a total of 36 end portal blocks are generated. In the console edition, there is only one portal per world, so only 12 are generated.

Usage
Using Eyes of Ender on end portal blocks inserts them to the top of the blocks. Once an Eye of Ender has been inserted in all 12 blocks, the End Portal will activate and the player can pass through to access The End.

End portals blocks have a front, which must face inward if you are to build a working End Portal. End Portals cannot activate in the End.

Redstone
End portal blocks will output a redstone comparator signal of 15 when an eye is present. If there is no eye in the frame, it outputs a signal of 0.

Video
Note: This video was made before the end portals gave off a redstone signal.

Trivia

 * When an end portal block is broken after being activated, the portal itself will not be deactivated.
 * When broken, these blocks make the same breaking noise as glass blocks.
 * An interesting feature of the end portal frame (and the monster spawner and slime block) is that they are transparent in their rendering only - unlike all other transparent blocks, they can have torches and redstone placed on them, conduct a redstone current, will suffocate mobs, and more.
