Minecraft Story Mode:Formidi-Bomb

The formidi-bomb, also refered to as the "F-bomb", is a powerful explosive from episode 3 of season one.

Crafting
Formidi-bomb is crafted with 8 gunpowder and a super TNT. According to Soren, attempting to craft it is very dangerous, as the ingredients are highly unstable when put together.

Appearance
The formidi-bomb looks like an ordinary TNT from the top, and like a command block from the sides. One side contains the letter "F". The bomb also has the white glow from the inside. Formidi-bomb is noticably bigger than other blocks.

Usage
The explosive power of formidi-bomb is capable of temporary disabling the wither storm. It is, however, incapable of destroying command blocks. After using the bomb on wither storm, it has split into three, not before releasing the survivors that were sucked into it.
