Cobblefish Mod

This mod as the cobblefish. It can't swim, it can't move (quickly). 
The fish is relatively rare, I might need to change it in the future. The fish can drop two items. The cobblefish itself and the rare stonefish. To get the rare stonefish you need the swimming stone enchantment, which will kill the fish instantly too (its relatively tough). The cobblefish can be smelted into a stonefish. All of the items are edible.

I got the inspiration from SuitedLlama, who gave some examples for cursed things in minecraft.

Use with own caution and always backup your worlds before installing mods.
