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. Underwater TNT can obtained by crafting or using Blocktopograph (Android only).

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.
