Jawbreaker Block

It can only be found in Jelly dungeons and is indestructible by survival means.

Obtaining
Jawbreaker Block makes up most of the Jelly dungeon. It cannot be mined or destroyed in Survival Mode and can only be destroyed in Creative Mode, therefore making the Jawbreaker Block unobtainable.

Natural generation
Jawbreaker Blocks generate in the Jelly Dungeon, along with Jawbreaker Light and more blocks.
