空ビン

• Upon use, stores an extra pickup. Using the Bottle again consumes the pickup.
• By using it in a room with a Gun Fairy , it's possible to capture it. Using the Bottle with a captured Gun Fairy will spawn a friendly fairy that heals in half-heart increments.
• The more health the player has, the faster the healing will be.
• After the player reaches full health and the delay between heals passes, the healing will permanently stop.
• After a few seconds of the fairy orbiting the player, it will disappear. Even if the fairy disappears before the player reaches full health, they will still be healed.

• Clearer Guon Stone - If the player has [クリスタルガンストーン] , it grants immunity to poison, fire, and electricity and it rotates at a fixed distance from the player while they are moving instead of on a slight delay. Shooting enemies while standing on fire or ice will burn or freeze them, respectively.
• Empty Vessels - If the player has [穴だらけの聖杯] , if damage is taken while Bottle is empty, it fills with a purple soul that deals 100 damage to all enemies in the room upon use.
• Mak Pak - If the player has [マカロフ] , its maximum ammo is increased by 30%, and while holding [マカロフ] , it occasionally fires a homing bullet at an enemy for free.
• When playing as The Robot , Patches and Mendy may give this item to The Robot even if it has not yet been unlocked.
• When playing as The Robot, the friendly fairy will do nothing and will disappear after a while, due to the fact that he has no heart containers.
• The item can be used on a health dispenser. If the dispenser holds two half hearts or more, the bottle will store a full heart.
• It is possible to use it in rooms with pickups locked in a cell to avoid opening the door.

• This item's ability to catch fairies is a reference to The Legend of Zelda .
• The line "heart container" is also a reference to the heart containers obtained from bosses in the Legends of Zelda series.
• In tandem with the Vampire, this item can be used to get infinite money. By saving a heart for later and then using the Bottle on it as it disappears, it will go into both the heart dispenser and the Bottle. The extra hearts can then be sold to the Vampire.
