Potatofun is a datapack, which adds several items, along with a recipe book which tells you what you need to craft them.
The native version is 1.14.4.
Any feedback, suggestions or recommendations are appreciated!

P.S.: The images are WIP (Work In Progress).

Items are crafted by dropping ingredients onto ground.
You can find recipes in a recipe book, which is obtained from clicking on a message in chat (Appears after a short while).

Here are the items:

Blessed Brick - A rather expensive block, which when placed will block mobs from entering or shooting inside in a 30-block radius. Can be destroyed using a pickaxe to reclaim it. The block will be placed onto the block below where you right click.

Pumpkin Berries Juice - A filling juice, which fills half of your hunger-bar right away.

Gilded Iron Shovel - An enhanced iron shovel, which will not break so easily.

Rainbow Wool - A wool which changes color like the rainbow. Can be mined normally in survival gamemode. In creative gamemode, you have to throw a stick onto it to remove it (You can throw it on it's side too).

Curing Potion - Potion which allows you to cure zombie villagers fed with a golden apple while under the effect of it. The effect is very short, so better do it quick.

Explosive Pickaxe - Pickaxe which mines common minerals in a 3x3x3 area (works on stone, diorite, andesite, granite, not cobblestone), this can be used on any pickaxe, retaining the enchantments and durability of the pickaxe.

Explosive Shovel - Shovel which mines common soils in a 3x3x3 area (works on grass blocks, dirt, sand, gravel), this can be used on any shovel, retaining the enchantments and durability of the shovel

Explosive Axe - Axe which mines logs connected to the first log chopped (works on any log and stripped log, not planks), this can be used on any axe, retaining the enchantments and durability of the axe

Rainbow Concrete - A block of concrete, which changes color like a rainbow. It can be broken normally in survival like normal concrete, and can be broken normally in creative like any other block. The block will only drop itself in survival.

Note: Might not be the best idea to use explosive tools near other players, it may cause unprecedented bugs.
