Seedling

The Seedling is a drop item from Plantera, who can only be summoned after The Wall of Flesh has been defeated. The seedling is used to summon the pet sapling. The pet Sapling follows the player around and cannot be damaged or killed. Players can only have 1 pet following them around at a time and do not need to carry the summoning item around after the pet has been summoned. After logging out or changing worlds the pet will still follow your character, the only time it despawns is if you summon another pet or if you die. Currently these pets do not do anything to help the player.
