Organic Armor

The Organic Armor is an Item that provides one extra, regenerative unit of health.

General Description
Organic Armor is an item that can only be found in the form of Golden Pupa loot. Upon being picked up, the player will gain one blue and green, plantlike heart, which appears to the right of all their other hearts. The next time the player is hit, this heart will be prioritized in taking damage, and will be the first unit of health to be lost. In it's place, a light blue "X" will appear instead of the usual  dark green one. Despite not behaving exactly like normal units of health, Thyme's downside will still trigger, causing the current day to lose 20 seconds regardless. Upon the next morning, the green heart will regenerate, allowing players to utilize this Item as a free, daily hit with little to no repercussions.

Comparison
Compared to all other shield related Items, the Organic Armor contains a unique attribute of the group, as unlike all others it does not feature a physical, interactable appearance outside of being initially picked up. Regardless, it is one of the most reliable Items technically capable of blocking damage, as it behaves almost identically to normal units of health. Unlike the others, players will not need to trigger any actions or move in a certain way in order to utilize this Item's function. Instead, Organic Armor will always passively activate the first time the player is hit that day. In addition, unlike similar Items, Organic Armor is capable of blocking all forms of damage, including fumes from Old Mech-Donald and Corpse-a-Copia's fist attack. Likewise, it is capable of blocking damage from Hotwire, making this the only shield related Item capable of pairing with Hotwire effectively. Similarly, since Organic Armor only works with getting hit it pairs well with Fraidy Fert, which rewards taking damage with Fertilizer. However, unlike all other shield related Items, Organic Armor can only appear in the form of Golden Pupa loot. This means that it requires significantly more effort to obtain, as it requires hunting and killing Tree Guardians, and even then is not guaranteed to appear each run. Furthermore, due to how Organic Armor does not appear within the player's Inventory, it is not possible for it to appear in the Time Capsule. Because of these two factors, Organic Armor is best seen as a luxury Item that works in conjunction with other Items.

Trivia

 * Taking damage with Organic Armor does not impede the player from being able to obtain the No pain, Only Grain Achievement. This means players can technically utilize this Item to take damage through any means during their run and still earn said Achievement.
