Jawbreaker Light

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

Obtaining
Jawbreaker Light makes up some 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 Light unobtainable.

Natural generation
Jawbreaker Lights generate in the Jelly Dungeon, along with Jawbreaker Block and more blocks.
