Bottle

The Bottle is an item in Cube Cavern: Reborn that can hold things such as water, souls, and gunpowder.

Water Bottle
Water bottles can heal you for 1 heart (2 HP). They can be refilled in ponds of water, or in the water fountain. They can also be bought in the shop for 24 coins.

Soul Bottles
Upon death, enemies sometimes drop souls. These souls come in red, blue, green, orange, purple and yellow. These can be stored in bottles to make soul bottles which are used to enchant daggers and swords, and are also able to dye backpacks. The Yellow Ninja also drops a BottleC, also known as Bottle Confidence, which can be used to upgrade swords and daggers in the same manner. Combining two BottleCs will create a bottleA, which can be used to craft skin items, such as DaggerA, SwordA, daggerT and Tear Gun.

Gunpowder Bottle
Upon death, enemies have a chance to drop gunpowder instead of souls. Gunpowder can be bottled similarly to souls. It can be combined with a normal backpack to create a Jetpack, and with a rock to make grenades. It can also be bought in the shop for 30 coins.

Bottle Of Crystal Powder
This item is obtained by combing a crystal shard and a bottle. It can be used to craft magic stones and magic water.

Punch
In the Halloween 2018 event, the fountain's water was replaced with fruit punch. It healed 2 hp and granted a speed boost like soda. This item is no longer obtainable.

Unpurified Water Bottle
Unpurified Water Bottles has one use and damage 2HP or one heart, obtained in the shop for 0 coins or by using a bottle on water in the blue dungeon, and can be Purified into a Water Bottle by the Pure Wand.

Other Uses
Two bottles can be crafted into binoculars, which can zoom in the FOV and are used to craft snipers with guns.
