Jelly Dungeon Lock

It can only be found in Jelly dungeons and is unobtainable by survival means. It can only be destroyed by using the Jelly Boss Key to open it.

Obtaining
Jelly Dungeon Lock makes up a very minor part of the Jelly dungeon, the door for the treasure room. It cannot be mined or destroyed in Survival Mode unless opened with a Jelly Boss Key, hence making the Jelly Dungeon Lock unobtainable.

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

Usage
Once opened, using the Jelly Boss Key, the Jelly Dungeon Locks will break and open allow access into the treasure room of the Jelly Dungeon.
