Underwater TNT

Underwater TNT is a block that can be used by the player to initiate a controlled explosion underwater.

Obtaining
Underwater TNT can be broken instantly with any tool, or without a tool. However, primed underwater TNT cannot be broken, as it is an entity.

Usage
Underwater TNT blocks can be activated the same way as a normal TNT block.

Behavior
Once activated, it will explode like a normal TNT block. However, unlike the traditional TNT block, it can damage blocks underwater. It can still explode in the air, however it will not work in lava.
